I just recognized something in your log in comment #10 which concerns me a bit. You seem to have a massive amount of multipath paths in your system - represented (as usual) as scsi disk devices - I can see a sdz and even sdax. Is this real and correct or is it due to a shaky SCSI/zFCP environment?
Please can you verify that the output of: lszdev zfcp lszdev zfcp --online sudo multipath -ll really fits exactly to your physical zFCP/SCSI setup of your environment? (and share the output) A shaky disk environment with temporarily unavailable devices or changing or unstable paths 'could' be a reason for rsyslog no longer being able to write to the underlying device. An btw. I also came across this: https://www.mail-archive.com/linux-scsi@vger.kernel.org/msg83837.html We may should consider to ask Steffen Maier to have a look at your (zFCP) environment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896575 Title: [UBUNTU 20.04] syslog daemon stop running unexpectedly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1896575/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
