Hello Grant,

I can't remember if I've offered this advice to you before or not, but have you tried running in high traffic mode, but setting MaxServers to 0 (this is the default in the latest ICs)?  Here are the settings we run for FrozenCPU:

Variable  TRAFFIC  high

ifdef TRAFFIC =~ /high/i
Message High traffic settings.
HouseKeeping 2
#MaxServers   10
MaxServers   0
PIDcheck     600

Do the IC or Apache logs saying anything about what the cause of those intermittent 500 errors might be?  We've found that most versions of IC, running on the latest perl, to be stable.

Good luck,
