Gerry,

it looks like your system goes berserk while performing a syslog.
I recently made a couple of cleanups on the specific logs that
caused your problem. It may sound silly, but there was some mismatch
between the format and the arguments supplied to syslog. 
Even if there's only a remote possibility this was the cause, please
check REL_ENG_2 before further investigation goes on.

Thanks, Pierangelo.
