This starts to get an interesting challenge now. :) Unfortunately one can't inspect the system in the way I would like to do, but anyhow... lets continue with the brainstorming: The php source code files might be written on bad blocks(?), or you might have hardware error with the RAM (unlikely - see below)... Maybe you should consider running a disk diagnostic tools, if that does not yield anything you might want to try to swap RAM - however if RAM was a problem, you should see randomly crashed processes to, which I understand you do not see. Does the hard disk get cooled down enough? I seen a database server that had a cooling problem with the hard disk because they was not spaced enough and became over heated and start to fail after the system been operational for a while. Another thought: have you just tried to replace the binary executable? E.g. replace the php interpretor with the one on the server that works.
