Hi Managers,
This is the lame excuse of the century... Well, I did not past any
summary since none of the answers proved to do something. We were running
solaris 2.4 on NFS clients. UPgrading ( a few months ago) to solaris 2.5-1
seems to have cleared the problem. We cannot tell for sure since this problem
was only happening one day in a month - the one I wanted to save for my family -
Best regards,
- gg
