Not sure, haven't rebooted yet to make sure it happens again. The hardware is a Dell Dimension 630, Dual Xeon PIII 550mhz, 768mb of RAM. It's been my main machine for a number of years now.

I thought I saw something float by where someone had raised some new locking or count variables? I dunno... I'll work on it tonight and see what happens after another reboot.
