could it be related to NFS (locking?) between your CentOS-6 clients
and NFS shared SGE directory?
or readdir failure such as:
http://bugs.centos.org/view.php?id=5496
Aside: Wow, NFS in 6.2 seems rather wonky. We've also hit this
<https://bugzilla.redhat.com/show_bug.cgi?id=770250>.
That being said, our SGE directory isn't NFS shared. We use local spool
directories and local SGE installations on all the nodes. The only thing
that's NFS mounted is $SGE_ROOT/$SGE_CELL/common so that we can have a
shadow master.
