Subject: soft lockup
Date: Thu, 28 Jun 2007 16:52:49 -0700 [thread overview]
Message-ID: <20070628235249.GM32531@ligo.caltech.edu> (raw)
I am currently getting a soft lockup every few minutes on a Sun X4600M2
(8 x Opteron 8218) running 2.6.20.14 plus Tronds revalidate-the-fsid patch
and Jeff's O_EXCL-OPEN patch. The machine is still usable but a bit slow and
currently the rpciod/0 thread is being reported as using 100%CPU by top.
Any ideas?
Thanks.
