As long as you're using PHP in a 'prefork' MPM environment (as the post 
you quoted suggests) then you shouldn't have any real problems. I've 
been running PHP on Apache 2 for quite a while and it hasn't given me 
problems, though I admit, I've always used Session4 for sessions of 
late, so I haven't tested Session '3' on apache 2.

My understanding of the issue is that thread safety is only a concern 
with PHP's modules, not any code that may be written in PHP.

Well, as you mentioned, your problem is strange enough that I don't have 
any good idea what would be causing it. Are you using the 
PHP3-compatible session class for PHPlib pretty much as-is, or have you 
modified it somehow? If you're using the User class, same question. The 
problem you describe would have to be in one of those two areas--you 
might want to make sure that your class isn't getting confused with user 
data and session data, since they're both stored in the same table by 
default.

Upgrading to session4 may help you--and it may not. But it's something 
to try. If you can send more details about what exactly is going on 
(maybe you can add some debugging code to your scripts that prints 
messages to a log or something), then I might be able to give a better 
answer.

Good luck!
