Thanks for a bug report. The error of the crash is "Creating pipes for GWakeup: Too many open files", which means that the limit of opened file descriptors was reached. Looking into the list of opened files, there are opened 1024 of them, most of them being eventfd, which suggests a leak of some structure which uses them. If I recall correctly, it's a GMainContext/GMainLoop and GCancellable, for those being used the most often. The backtrace also shows that there are ongoing searches for contact photos; maybe it's related, maybe not. It would be good to try to figure out after which action the eventfd is left opened. You can get the count of opened eventfd descriptors with this command: $ lsof -p `pidof evolution` | grep eventfd -c It can increase after some action, for sure when you'll select a new message to be viewed in the preview panel, because it'll open a new thread(s) with search for the sender's photo. Once these searches are done (or cancelled), the eventfd count should decrease again.
Hi Milan, I tried the command you've mentioned above and got these values at different times - [asinha@cs-as14aho-2-herts-ac-uk ~]$ lsof -p `pidof evolution` | grep eventfd -c 837 [asinha@cs-as14aho-2-herts-ac-uk ~]$ lsof -p `pidof evolution` | grep eventfd -c 835 [asinha@cs-as14aho-2-herts-ac-uk ~]$ lsof -p `pidof evolution` | grep eventfd -c 841 [asinha@cs-as14aho-2-herts-ac-uk ~]$ lsof -p `pidof evolution` | grep eventfd -c 841 [asinha@cs-as14aho-2-herts-ac-uk ~]$ lsof -p `pidof evolution` | grep eventfd -c 840 [asinha@cs-as14aho-2-herts-ac-uk ~]$ lsof -p `pidof evolution` | grep eventfd -c 840 [asinha@cs-as14aho-2-herts-ac-uk ~]$ lsof -p `pidof evolution` | grep eventfd -c 840 The last few are from when I'd clicked "Send/receive" and it was syncing my 6 e-mail accounts. Cheers, Ankur
Thanks for the update. The cunts do not look that bad. The 840 is quite many files being opened, but the count doesn't increase after the Send/Receive, thus that part seems to be safe for now. I suppose that certain actions will increase the count, but will not decrease it when the action is over. That will be the sign on the leak. Note that some actions can take longer to finish, even without any user visible feedback.
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
