I'm confused. Is it the same server, same kernel & other hardware/software specs ? If you try 2 different debian distrubtion, there may be some changes in PHP/libraries. What you need to do to isolate the problem is leave PHP alone because you have the start delay even without it. calling exit() within suexec or returning just before the execv is a good test case. Can you test on your 2 servers with the patched suexec? Test multiple times with apache stop or reboot commands between to be sure the delay is the same. If it's the same delay, it's likely to be a hardcoded time value; if the delay changes, it can be a library load time or a cache prefetch time. Are you installing mod_fcgid with the automated system (apt-get) or compiling from source? I know many debian users love to use the apt-get system, but this is really not what you want to do to test a specific problem in a specific module version. You have to only modify 1 thing between your tests or you won't be able to isolate the problem. It's like you have a cold AND headaches, and you take 2 different pills: you won't know which one made your headaches disappear. >> Oh, and add something like -s 4096 to the strace command to see more on >> the socket read. >> > > Strace with -s 4096: nothing relevant here Gabriel ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
