Well I commented out memcache as save_handler in php.ini and went back to
saving sessions by files. And I haven't had php crash on me since, the output
is below for the .diff file.
my problem had to do with memcache though, the php pecl version i'm running is
memcache-2.2.7. It almost doesn't make sense though, because now I have 300
plus session files that only take up 15KB total space. And if that's all it was
taking up in memcache, I don't know why it would cause php to crash.

what the failed diff of these session test scripts?
like the output of:
cat ext/session/tests/ext/session/tests/rfc1867.diff

These same errors still occur in 5.4.14 I think I have a better clue of why
this is happening. When I upgraded to 5.4.14 I ran the make test and got these
results:

No, I haven't tested it with Xcache disabled. I didn't even think Xcache would
be an issue since it doesn't interact with the writing of the sessions. I will
disable Xcache for a few hours and see what results, I get thank you for the
response.
