You get what appear to be random parse errors on any page while running the eZ-publish content management system. 

We installed this on machines with a single processor and on machines with multiple processors and the results we saw were that on a single processor the content worked fine with multiple requests. Where as with the multiple processor machines even if we did two refreshes in quick succession we got a parse error.

We checked the code to see if it was corrupt, this was proved not to be the case. What we think is going on is that the CPU's are locking the files that are being accessed. Therefore those which get accessed a lot such as the sessions are causing problems.

Tried the compiled version (2nd one) and we couldn't actually get it to work.

Maybe it's not too much work to tell why you didn't get it to work?

Sorry, same issue as before.
