Description Jonathan Briggs 2016-04-27 21:39:29 UTC 
Description of problem:
After running for some time Firefox runs out of file handles. It then begins writing errors to the journal like this:

Apr 27 15:25:06 felis firefox.desktop[5422]: (firefox:5422): GStreamer-CRITICAL **: gst_poll_write_control: assertion 'set != NULL' failed
Apr 27 15:25:06 felis firefox.desktop[5422]: (firefox:5422): GStreamer-CRITICAL **: gst_poll_write_control: assertion 'set != NULL' failed
Apr 27 15:25:06 felis firefox.desktop[5422]: (firefox:5422): GStreamer-CRITICAL **: gst_poll_get_read_gpollfd: assertion 'set != NULL' failed

And

Apr 27 15:25:19 felis firefox.desktop[5422]: console.error:
Apr 27 15:25:19 felis firefox.desktop[5422]:   Could not write session state file
Apr 27 15:25:19 felis firefox.desktop[5422]:   Message: Unix error 24 during operation open on file /home/zlynx/.mozilla/firefox/1wiu6mtz.default/sessionstore-backups/recovery.js.tmp (Too many open files)

The command lsof -p [firefox PID] shows (this is an extract):

And after that it is unix stream sockets until 1023u.

Version-Release number of selected component (if applicable):
firefox-45.0.2-4.fc24.x86_64

How reproducible:
So far every time after about an hour.
Comment 1 Jonathan Briggs 2016-04-27 21:42:05 UTC 
Oh and I am reporting this against Fedora 24 instead of Firefox upstream because Firefox was working very well for me under Fedora 23. This could be a recent Firefox bug but I sort of doubt it.
Comment 2 Jonathan Briggs 2016-04-28 23:26:38 UTC 
After the recent Firefox update to version 46 I no longer see this problem.

Could have been a GTK 3 issue.
