Troubleshooting CF8 + CentOS5 lockups

Question

Hi guys, I was hoping you might be able to help me troubleshoot this issue I'm having.  We have 5 identical servers running our application.  They are all configured identically.  About a week ago, web1, our first node, started locking up a few times a day, with the coldfusion process jacked up at 100% cup usage.  I have verified the settings are identical to teh other 4 boxes, and I have copied over a fresh copy of the codebase.  I have also applied all updates on the misbehaving box, as well as updateing to CF8.01 hotfix 4, and JRE 1.6.0_23.  I have cleared all cache, and I have rebooted the machine several times.  The hangups are still happening, seemingly at random.
Here's the specs on the machines:
Dell 1950's, Two dual core 3.0 GHz xeon's, 8GB memory, two 147GB 15k scsi in raid 1.
Cent OS 5.5 64 Bit
Coldfusion 8.01 Standard (32 bit)
Apache 2.2.3 (32 bit)
Here are some log file snippets from when the machine is experiencing problems:

It looks like something is causing CF to use an absurd amount of memory, and these are the symptons of its death roll.  I dont believe that this is a problem requiring simple jvm.config tuning.  I think something is very broken with the CF server, I just dont know how to trace it properly.  This application has no such problems on any of the other web servers.
Thank you again...
