in reply to Forcing modperl processes to restart after N requests


The simplest solution is to let Apache handle it: There is a configuration parameter MaxRequestsPerChild. On default installations it's set relativly high. Tweak it for you mod_perl centric processes.

Look at for some hints on memory usage.

Look for documentation of $r->child_terminate. With that method you can force the Apache child to exit gracefully at the end of the whole request lifetime. Combined with a process global counter you could implement an own controlled way of exiting after an certain count of requests. With this way you could be sure that a certain amount of perl handled requests were served (using Apache for static and dynamic content).

Best regards

P.S.: mod_perl mailing list is the right target for these questions. Thorsten Förtsch regularly answer fast and very competent. (

    Sounds like MaxRequestsPerChild is what I need. Thx.

    Strangely enough, I didn't come across it, even after 30 mins of google for things like "mod_perl forcing process to restart".
