Memory leak?

I used phorum31b and experienced a CUP has be eaten problem. I asked phorum developer the same help. But think it may get help form php people. The usage of phorum is nothing but a couple of DB queries written by PHP. I experienced a randomly problem after phorum send requests to Mysql by PHP script. MySql is built as Script interpreter on Apache. the problem looks like this: once a client send a request (through phorum by php script) the server shows the following error message: (see attached image1) "PHP caused an invalid page fault in module PHP.EXE at 0177:004263e8. Registers: EAX=33353225 CS=0177 EIP=004263e8 EFLGS=00010202 EBX=006bee6c SS=017f ESP=006becc0 EBP=006bfda4 ECX=020ca520 DS=017f ESI=013e9564 FS=5faf EDX=00000000 ES=017f EDI=00485754 GS=0000 Bytes at CS:EIP: 89 50 04 51 e8 d3 b8 01 00 59 c3 90 90 90 90 90 Stack dump: 0043a5e9 020ca530 0042c3f8 004856a0 020ca530 00485710 00485710 006becec ffff8000 006bf9b8 00430ce9 013e9530 006bee0c 006bee4c 006bfd90 00000001" the Apache server error_log shows: "Premature end of script headers: c:/php3/php.exe" And the memory has been eaten. I am not sure it is PHP problem. But hardly say it is MySql problem since other allication using MySql is ok. Help please. -- ********************************************** Dr. Gangmin (Gary) Li * Research Fellow Knowledge Media Institute (KMi) The Open University, Milton Keynes, MK7 6AA Tel: +44 1908 858519 * Fax: +44 1908 653169 http://kmi.open.ac.uk **********************************************
