One thing I noticed was that this only really happens after transferring 
large amounts of data to the disk. For example Neil's CVS update or my 
dump/restore to get the files onto the raid sets.

After I re-partitioned and updated the raid filesystems, I noticed that 
the problem had gotten worse - horribly worse. Many (random) apps would 
core-dump and many services died during rc due to library problems.

In a fit of panic, I mounted a cd image of 1.6ZI and re-extracted all 
the sets one by one (rebooted after just the kernel.)

Now the machine's been up 2 days without a hitch. As soon as something 
happens, I'll let you know.

Also - in case it matters, this is a MP machine...
