Hi All, I have a high traffic mod_perl2 web server (40 requests/second and all are dynamic data - no images or static html) and I have a slow memory leak in mod_perl2. I haven't tracked the leak down yet, but to deal with it I have set MaxRequestsPerChild to 5000. I'm using the worker MPM with the following config:
ServerLimit 5 MaxClients 250 StartServers 5 MinSpareThreads 250 MaxSpareThreads 250 ThreadsPerChild 50 Since I set MaxRequestsPerChild to 5000 I noticed that the number of httpd.worker processes at some point doubles from 5 to 10. It's as if the old processes aren't being shut down properly once they've served their 5000 requests. I have mod_status installed and it still only shows me 5 processes with their respective threads even though 10 appear to be running. ps shows the 10 processes and that only half of them have their CPU time increasing - the others don't seem to be doing any work. Also, it seems that the half that are working are fairly new processes and are being killed and re-spawned in accordance with MaxRequestsPerChild and the others are just sitting there. I'm running Fedora Core 6 64bit with the standard RPM distribution of mod_perl and Apache/2.2.4. The binary httpd.worker has the following statically compiled in: core.c worker.c http_core.c mod_so.c I have the following DSO modules in my config: LoadModule log_config_module modules/mod_log_config.so LoadModule expires_module modules/mod_expires.so LoadModule deflate_module modules/mod_deflate.so LoadModule mime_module modules/mod_mime.so LoadModule status_module modules/mod_status.so LoadModule alias_module modules/mod_alias.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule authn_file_module modules/mod_authn_file.so LoadModule auth_basic_module modules/mod_auth_basic.so LoadModule authz_groupfile_module modules/mod_authz_groupfile.so LoadModule authn_default_module modules/mod_authn_default.so LoadModule authz_host_module modules/mod_authz_host.so LoadModule authz_user_module modules/mod_authz_user.so LoadModule authz_default_module modules/mod_authz_default.so LoadModule perl_module modules/mod_perl.so LoadModule apreq_module modules/mod_apreq2.so Any help or suggestions would be much appreciated. Regards, Mark.
