>From a uname -v, they both appear to be #1 SMP Fri Oct 13 17:56:20 EDT 2006.
Here's a uname -a on each: ServerB (B as in bad): Linux expurgate2 2.4.21-47.0.1.ELsmp #1 SMP Fri Oct 13 17:56:20 EDT 2006 i686 i686 i386 GNU/Linux ServerA (A as in awesome): Linux expurgate1 2.4.21-47.0.1.ELsmp #1 SMP Fri Oct 13 17:56:20 EDT 2006 i686 i686 i386 GNU/Linux I asked one of our Unix admins that very question, but he unfortunately is not the one who built the servers, and didn't know. Is there any way to tell now if they were compiled with different memory config options, or does the fact that they have the same kernel version eliminate that possibility?
