I am using teh CentOS5 distro, but not the CentOS K12LTSP distro.

This behavior just started. The server has been running flawlessly
since early August.  I haven't applied any updates to the system
unless they were to fix a critical security issue.  I try to 'freeze'
system configurations at the start of the school year to minimize

Top shows kjournald and also several nfsd processes.  Both times it
has happened have been on Monday morning.  I am wondering if it might
not be somehow related to the full backups that run Sunday night.  The
backups show that they have completed by the time school starts.  I'll
try setting the full backups to run Saturdays instead.  The only other
thing that comes to mind is that samba profiles are kept on this
system but I don't see how that would just now be showing up.
