FYI. Bug exists in 2.6.6
I hit this bug 3 times within the last 2 weeks with similar message on my nfs
server. It ran fine for the first 4 weeks. I'll try nfs_fsstress.sh see if I
can reproduce. Server stores maildirs & imap server for the maildirs. Mean
while is there anything I can do to reduce or to avoid this? Thanks in advance.
Here's my config:
XEON 2Ghz
