[Beowulf] NFS+XFS+SMP on kernel 2.6

We set up a 160 node cluster with a dual processor head node with 2GB
RAM. The head node also has two RAID devices attached to two SCSI
cards. These have a XFS filesystem on them and are NFS exported to the
cluster. The head node runs very low on memory (7-8 MB). And today I
ran into a kernel bug that crashed the system. Google suggests that I
should upgrade to kernel 2.6.11, but that sounds very unpleasant. I am
thinking of putting the raid boxes on a different box. Will separating
the file-server and the head node give me back stability on the head
node?
