Gilbert,

I've been trying. Unfortunately, everything looks good. The pqact(1) processes 
are receiving a SIGSEGV when they call the regexec(3) function to match a 
product-identifier against a compiled regular-expression and there doesn't 
appear to be anything wrong with either. I also ran pqact(1) under valgrind(1) 
and there were no invalid memory accesses or relevant memory leaks.

At this point and given the following:

1. Weather3 appears to be the only system on which this happens;
2. Nothing appears to be wrong with the code;
3. It appears to be happening with increasing frequency; and
4. Weather3 had a panic attack;

I'm beginning to suspect a hardware problem; specifically, bad memory.

Can the memory be checked?
