 I found another source of memory leakage this morning at 4am when
 "daily" started up. I watched vmstat as memory went from ~70% used
 (with essentially nothing running) to ~98% used and was never
 recovered and had to reboot. I had started suspecting this as every
 morning I usually have to reboot the box to make it usable.
