I installed php to utilize phpbb forums on a dual CPU high end server.  Win2K MSSQL 7.0.  Performance was ok but now having only 10,000 posts (and having moved to another server single P3 CPU) I cannot get anything to return from the database.  CPU pins at 100% until my forums eventually timeout.  All utilization is coming from MSSQL Server (cpu usage and memory).

I did have huge memory leak problems coming from MSSQL server on the first server (was using latest PHP installed around Oct/2002).  This seems to have gone away (PHP 4.3) but I can't tell for sure since I can't use the forums yet.

I have another set of forums on the same server (PHP/MSSQL) with only a few posts and they at least work.

I can query the database no problem outside of PHP with excellent performance.

I did search around in these bug reports and wasn't able to solve my problem.

Thank you.

This problem looks like it is solely related to the phpbb forum code.  I have isolated the problem there and submitted a bug report to them.

Performance is still overall sluggish and cpu intensive, but not a bug :)

Not PHP bug -> bogus. Thanks for reporting.
