[Ocfs2-users] 3.14.21 Kernel warning

Mon Nov 24 09:41:30 PST 2014

I've recently upgraded my kernel from 3.10.25 to 3.24.21 and I've been
seeing these warnings from the kernel. The frequency is about 2 or 3 times
per day, and only in the early morning when there's a lot of load and
activity due to system backups. Should I be worried about this? I tried
kernel 3.16 recently, but there's just too many stability problems there.
