[Lustre-discuss] Client lockup: Problems with bug 22935?

Hi all,
we are running Lustre 1.8.3 on Redhat 2.6.18-164.11.1.el5 kernels and on
one client the Lustre module 'crashed' twice in 24 hours:

The first error message looks like we are running into bug 22935. For
the second error I could not find anything in bugzilla.
There are no errors on the Lustre servers.

Could those two problems be related?

Does anybody know a workaround for this? Should we disable statahead for
now?

Happy to provide more information.

Thanks for your help,
Karen
