[Ocfs2-users] BUG: soft lockup - CPU#1 stuck for 61s

[Konstantin Tikhonov]

Hi,
I've discovered that when the webserver is working o2net process
usually appear in the output of "top" command. But it disappears when
I start some long-lasting process like log analyzer or logrotate. I
see only logrotate process utilizing 100% cpu time and there no o2net
nor webserver processes. After about 90 seconds the reported problem
occures. I tried to "nice" logrotate and even work with log-files
which a not accessed by other nodes, but it didn't help.
