Still seeing this issue with package and tracking FIFO on log in log out lightdm.x86_64 1.25.0-1.el7 lightdm-gobject.x86_64 1.25.0-1.el7 lightdm-gtk.x86_64 1.8.5-19.el7 lightdm-gtk-common.noarch 1.8.5-19.el7 [root@caeusadm tmp]# lightdm -v lightdm 1.25.0 [root@caeusadm tmp]# lsof -p 13696 | grep FIFO | wc -l 188 [root@caeusadm tmp]# lsof -p 13696 | grep FIFO | wc -l 190
Increments by 2 for every log in log out and never frees them up. When it passes open file limit (currently 1024) lightdm crashes and all users lose session. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1190344 Title: Daemon end of session/greeter pipes not closed Status in Light Display Manager: Fix Released Status in Light Display Manager 1.10 series: Fix Released Status in Light Display Manager 1.12 series: Fix Released Status in Light Display Manager 1.2 series: Fix Released Status in lightdm package in Ubuntu: Fix Released Status in lightdm source package in Precise: Fix Released Status in lightdm source package in Trusty: Fix Released Status in lightdm source package in Utopic: Fix Released Status in lightdm source package in Vivid: Fix Released Bug description: [Impact] LightDM doesn't close the server side end of the pipes used to communicate with session processes and greeters. This means each session/greeter that is created leaks two file descriptors eventually leading to the system stopping it from creating new pipes. [Test Case] 1. Start LightDM 2. Check how many pipes are open # lsof -p {lightdm_pid} | grep FIFO | wc -l 3. Create sessions by either cycling between users in Unity Greeter or logging in and out 4. Check how many pipes exist using step 2. Expected result: No more pipes should be open Observed result: Many pipes remain open [Regression Potential] Low. Fix is to close pipes when finished with them. Tested with regression tests.
