| By lock up I mean the machine is completely dead. Not 100% CPU busy, not out of memory, etc. but completely unresponsive

This sounds like a kernel / hardware problem (like Ken, I've never come across anything like this, nor seen reports from anyone else along these lines FWIW). You may have some success extracting additional diagnostics via a kernel debugger, and/or sysrq-'t' from the console - https://www.kernel.org/doc/Documentation/sysrq.txt

| Does PCP load or include any kernel modules when it is started?

No it doesn't. Your log file and configuration file look in good shape too - no warnings/errors there, so from a PCP point of view, everything looks normal with your machine setups.
