I do not believe so. What ever it is definitely appears related to swapping/paging somehow. I get these LA spikes in the several hundreds, the disk light is on solid for 2-3 minutes, then it all goes away. System accounting doesn't show any unusual pattern of apps being run. The vast majority are perl scripts. There's about 1100 processes on the machine, give or take a few, with about 80MB RAM free. NFS is compiled in, but not used. I have also disabled ntpd thinking something was hanging there, but no dice.
