I've had a similar problem with an IBM Thinkpad A21p. The machine would 
slowly start to lock up until the only thing it would respond to were 
pings. This would usually occur when the filesystem was under a heavy 
load (like untarring openoffice). I managed to trace the problem to 
snapshots that were about 40 days old (I keep old snapshots around for 
CYA purposes). After deleting the old snapshots, the system functioned 

I've been running it pretty hard now for the last few weeks and it 
hasn't locked up once. Whether or not the snapshots were the cause of 
the problem or just another symptom I can't really tell but deleting 
them definitely cured the problem. Right now I have a filesystem 
snapshot that's about a week old and it seems to be just fine.
