This is really a bug.
on my p4 2.4c + 865G + 1G ram, win2k3 server, apache 2.2.3.0 & php 5.2,
this happens all the time.

Error in CPU IDs in previous comment, from microsoft support article ID
252867:
Processor enumeration on computers that use hyperthreading first assign
processor numbers to the primary logical processor for each processor
and then assign numbers to the secondary. For example, for dual
physical processor computers with hyperthreading, the first processor
has logical processor 0 and 2, and the second processor has logical
processor 1 and 3.

It appears that setting the CPU affinity of the apache http process to
a single physical processor stops the crashing...
Setting the server to NOT use the second hyperthreaded core of the
xeons (i.e. CPUs 0+2 or 1+3) seems to solve this random crashing.
Will test with a prefork MPM.

I'm currently unable to track down a single script/function which
causes this error, and am therefore unable to provide a code sample.
I realise that the bug report is pretty useless without reproducable
code, so I'm still investigating and trying to track down the exact
cause of the crashes.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
