Possible Memory Leak in CGI script invocation

• Additional Comments From i.t@ithum.de 2002-11-30 15:53 ------- Observations for an SSL-vhost on Win2k with Apache/2.0.43 (Win32) mod_ssl/2.0.43 OpenSSL/0.9.6g PHP/4.2.4-dev I've proofed the system, httpd.conf and php.ini, opened the server-status. php scripts have been cleaned up due to not deleted temporary files; behavior is better than before, but during many simultaneous requests - most sites are php scripts - the server seems to hang, CPU load goes to near 100 percent, memory usage may have doubled from 250 over 500 MB RAM. I've instructed a local admin to stop and start the server (not graceful) in such a situation. Otherwise it may take 10 to 20 minutes until the server cleans up. No request is possible in this phase. Server status shows a lot of long running reading requests. Example: 0-1 1064 0/461/461 R 734 0 0.0 1.71 1.71 ? ? ..reading.. 0-1 1064 0/0/403 R 756 0 0.0 0.00 1.32 ? ? ..reading..

"Fortunately" this happens mostly only once a day during business hours at Monday and Thursday when many customers are active. php scripts are in further cleanup process, but that looks more like a bug in Apache and/or Win2k.
