Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Previous Comments: ------------------------------------------------------------------------ [2003-05-05 03:20:29] jakub at icewarp dot com Still the same. Btw. what I testing now is not the COM object issue but simple HttpExtension call which leaks the memory. Each call to the ISAPI module leaks some memory. Tell me. Thanks ------------------------------------------------------------------------ [2003-05-04 03:30:46] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2003-05-03 10:22:59] jakub at icewarp dot com I was wrong about the [EMAIL PROTECTED] it is called by Windows automatically. However I have found for instance this. If you load the ISAPI module and free it in a cycle again it does not free the memory. for ($i=0;$i<1000;$i++) { lh = loadlibrary("...isapi.dll"); freelibrary(lh); } After 200 cycles the process consumes 50MB. I don't think that should happen. What is wrong? ------------------------------------------------------------------------ [2003-05-03 04:02:26] jakub at icewarp dot com Some more info I have found. The DllMain function from the ISAPI dll is incorrectly exported and has the name [EMAIL PROTECTED] so it cannot be called by the web server. When you call the PROCESS_ATTACH and DETACH DllMain calls it raises and exception. THREAD_ATTACH and DETACH work fine but still the memory leak is there. Each call to the HttpExtensionProc leaks about 1kB of memory. Please try to have a look at it J ------------------------------------------------------------------------ [2003-05-02 08:44:36] jakub at icewarp dot com I have found out there is a worse problem. When calling the ISAPI DLL function HttpExtensionProc(Extension) to process the PHP session it leaks some memory. If you remove the call it does not leak any memory. I also made sure the WriteClientProc and such procedures in the Extension struct are empty so there could not be any leak from within the web server engine. I also tried to unload the ISAPI dll and this did not free the memory either. When run the 1000x HttpExtensionProc(Extension) to a very easy script like the following: <? echo "Hello"; ?> It leaks about 500kB. I'm not a Linux guy but I suppose if there would be a leak on Linux everybody would already know so I think it might be the ISAPI module problem only. Hopefully.
