Mail had been freezing up for several seconds at a time, so I closed and reopened it, and the reopen never got far enough to show the UI. In Activity Monitor, the trace looks like it's stuck in a GPGMail semaphore. The last thing I did with GPGMail was install the latest version, which I did when I got the prompt that the previously installed version had expired. I've attached the trace from Activity Monitor.

How do I get this unstuck?

   After a reboot Mail seems to be working again, we'll see if it starts freezing up again. Before the reboot I noted a few GPG processes running:

   2943 ?? 0:00.00 (gpg2) 32872 ?? 0:18.49 /usr/local/MacGPG2/bin/gpg-agent --daemon
   32878 ?? 0:00.01 /bin/bash /usr/local/MacGPG2/libexec/shutdown-gpg-agent
   32955 ?? 0:13.95 /opt/local/bin/gpg-agent --write-env-file --no-use-standard-socket --launchd
   34432 ?? 0:31.60 /Library/Application Support/GPGTools/org.gpgtools.Libmacgpg.xpc
   79544 ?? 0:16.51 /usr/local/MacGPG2/libexec/MacGPG2_Updater.app/Contents/MacOS/MacGPG2_Updater /Library/Application Support/GPGTools/GPGMail_Updater.app/Contents/MacOS/GPGMail_Updater
   79545 ?? 0:15.89 /usr/local/MacGPG2/libexec/MacGPG2_Updater.app/Contents/MacOS/MacGPG2_Updater

   After the reboot, it's mostly similar:

   470 ?? 0:00.22 /Library/Application Support/GPGTools/org.gpgtools.Libmacgpg.xpc 571 ?? 0:00.05 /opt/local/bin/gpg-agent --write-env-file --no-use-standard-socket --launchd 577 ?? 0:00.01 /bin/bash /usr/local/MacGPG2/libexec/shutdown-gpg-agent 650 ?? 0:00.04 /usr/local/MacGPG2/bin/gpg-agent --daemon 982 ttys001 0:00.00 grep -n --color=auto -i gpg

   Was the original problem with the updater? Do I need to check that GPGMail is not half-updated?

   Hi Shad,

   it's really strange this problem is reoccurring on your system.
   Could you open Console.app and search for "org.gpgtools.Libmacgpg" and post the messages you find here?

   Thanks!

   Before the reboot searching Console for gpg got zero hits. Now there are 3, from long after Mail got back to normal:

   Did you run the GPG Suite beta 5 update or use automatic update? If the latter, I'd suggest to run the GPG Suite from our homepage over it just to make sure everything is on the latest release status.

   So after that, did any issues persist? Any observations from today?

   All the best,
   steve

   I'm not aware of any automatic update, but that's essentially the point of having automatic updates. When I got the prompt that the previously installed version had expired it would not update automatically. From my browser history it looks like I downloaded GPG_Suite-2015.02-b5-1161.dmg on February 13th (more recently than I thought), any update after that was automatic; what's installed now says it's version 2.5b5 build 891b.

   I haven't had any issues since rebooting. If it does happen again, the first thing I'll do is download & reinstall the GPG Suite.

   Something similar happened again today. This time it wasn't freezing up, it was taking forever to load a particular message thread. (There were signed messages in that thread, all of them outgoing messages signed by GPGMail.) Quit Mail.app and on restart it was again stuck in semaphore_wait_trap under GPGTaskHelperXPC. Killed Mail.app, reinstalled GPG_Suite-2015.02-b5-1161.dmg (no reboot this time), and it again seems to be back to normal. Again there were no GPG entries in Console before or after; this time there was no GPGMail_Updater running before or after. Why would reinstalling the same version make any difference?

   Happened again today, Mail crashed while idle, and hung on relaunch. Same GPG processes running, no GPG entries in Console. More threads in sample this time.

   Can one of you point me to where in the code the semaphore wait happens? What's involved in getting this to run in a debugger?

    Hi Shad, thanks for keeping an eye on this. GPG Suite b6 is out and you might want to install the update.

    I don't think it fixes this problem since we have not working in that area. Nonetheless it would be good to keep testing with the latest beta.

    Have you found any steps to trigger this issue? So far it seems to come and go pretty random.

    Kindly,
    steve

    Sam problem here. Mail hangs on startup. Reinstalling gpgtools solves it for e while.

12. 12 Posted by Tom on 30 Mar, 2015 04:17 PM

    

    Same for me.

    It happens from time to time when I send an encrypted message. The message is stuck in "saving to drafts/outbox/whatever" and I am not able to recover it anyhow. The whole Mail app is then still responsive, however in the activity window, I can see that every activity is stuck. I'm not able to download new mails or send one.

    Probably the most annoying thing about it is, that the mail I supposed to send is completely gone. Sometimes I don't even notice that it was not sent, since there is no feedback from Mail.app (you can only see the stuck message if you open the activity window). So I first realised this a couple of weeks ago when someone told me that I have not responded on his mail (which I actually did).

    Cheers,
    Tom

    Something similar happened here, starting Mail just gives me a spinning beach ball.

    It seems to be related with a couple of left over processes from earlier runs, I found:

    $ ps auxwww | grep -i gpg
    mjl               805   0.0  0.1  2741608   8224   ??  S    24Mar15   0:07.86 /Library/Application Support/GPGTools/org.gpgtools.Libmacgpg.xpc

    I killed 805, 739, 593 and suddenly Mail.app stopped beachballing and openened its window.

    I've also got a

    Thank you for all your reports and log files.

    It looks like GPGMail wants to connect to the XPC service while it's not yet up and running. Curiously enough, we were not yet able to reproduce this issue, but should be able to work around it.

    I'll create a ticket for it and this discussion will be updated when the bug is fixed.
    Should anyone of you still happen to find a scenario to reliably reproduce this, it would be really great.

    Thanks.

    Happened again with 2.5b6 (build 916b) while trying to edit the outgoing server list from the send error dialog in a new message window. Hung on relaunch twice before I realized I had the Cisco AnyConnect VPN client running, but after closing that Mail hung on relaunch a third time. After rebooting the computer it opened normally (and I was able to update the server list and send that message). I'm also unable to download the nightly.

    Hi Shad and mjl,

    we had a glitch with the server cache and nightly channel updates. Should be fixed now.

    Could you please download and install our latest nightly build and see if the problem persists. That page also has sig and SHA1 to verify the download.

    All the best, steve

    Just had it happen again with build 930n, which I believe was a nightly build after comment 18. It happened at least twice (there was a 3rd hang which I didn't sample), and relaunching worked after killing the GPG processes that were running after the first occurrence:

      446 ??         0:55.99 /Library/Application Support/GPGTools/org.gpgtools.Libmacgpg.xpc
      658 ??         0:41.64 /opt/local/bin/gpg-agent --write-env-file --no-use-standard-socket --launchd

    92498 ??         0:00.00 (gpg2)
    

    This time there were some messages in Console.app, I think they're all from after closing the previous instance of Mail.app:

    2015-May-01 21:13:59.892 Mail[28855]: Loaded GPGMail 2.5b6 (7bf389b)

    This time I closed the previous instance of Mail.app because it had stopped sending outgoing mail to one of my accounts; I don't know weather that's related to GPGMail, or to this bug.

    Hi Shad,

    that is not the latest nightly version of GPG Suite. Please update to GPG Suite 1326n or later from here: https://releases.gpgtools.org/nightlies/

    Also please update your OS to 10.10.3 (via the Mac AppStore) which includes a ton of security relevant fixes. After that see if the issue persists.

27. 27 Posted by Shad Sterling on 04 May, 2015 01:45 PM

    

    Of course it's not the latest; when the glitch with downloading was fixed I updated. Wasn't that update supposed to have the fix for this hang? If the hang still occurs after the fix, I'd say there's some case where the fix doesn't work.

    I didn't realize you expected me to go to the site every day and install the new nightly. Is there any way to automate that?

    • Edit

28. Support Staff 28 Posted by Steve on 02 Jun, 2015 12:35 PM

    

    Hi Shad,

    any GPG Suite nightly build higher than 1325n should include the fix.

    If you want to receive nightly updates, please open GPGPreferences > Updates and select the nightly channel. Use any update interval which fits your needs.

    Let me know if that worked. Also did the issue reappear for you? If so, please copy all version info as described here into this discussion.

    All the best,

29. 29 Posted by Shad Sterling on 03 Jun, 2015 06:11 PM

    

    GPG Preferences doesn't show a version number for GPG Suite. I've changed everything to check daily, they were already on the nightly channel. GPGMail is now on 1004n.

    I haven't seen the issue since my last comment. I usually tell GPGMail to install on close, but I almost never close Mail; usually it gets closed when the system crashes, which I've started to think also prevents the install on close from running.
