I recognized kernel oopses in syslog when Amanda tried to backup this
host (maxdumps=3):

Jul 24 00:45:29 somehost kernel:
Same occured this morning when I drove sendsize by hand with maxdumps=3
but not with maxdumps=1.
Ok, I'll upgrade the kernel from 2.4.6-pre5-xfs to 2.4.7-xfs before any
further investigation...
