[Ocfs2-users] sudden crash, possibly OCFS was the cause?

[Florin Andrei]

Support told me this looks like a bug that was fixed in 
ocfs2-2.6.18-194.EL5-1.4.7-2

We're running 1.4.7-1 currently, and the kernel is older (2.6.18-128).

So, apparently, the bug (if that's what caused the crash) was fixed 
between 1.4.7-1 and 1.4.7-2.

I may give it a try. I was not aware you guys are doing important bug 
fixes between minor patch levels.
