http://issues.apache.org/bugzilla/show_bug.cgi?id=42473 Summary: Apache2 problem with MaxClient and/or TimeOut Product: Apache httpd-2 Version: 2.0.54 Platform: Other OS/Version: Linux Status: NEW Severity: blocker Priority: P1 Component: prefork AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] Dear all, we have a webmail platform based on Reverse Proxies + Apache + Squirrelmail. Lately we updated Apache's from 1.3.x to 2.0.54 (using standard Sarge Debian packages), since this update, we are watching that Apache reaches MaxClients often (once or twice daily), and the only one way to restore the service is to restart the daemon. Luckly, we have been able to test a "hanged-up" server, and we made several test/meassures: 1. We noticed that MaxClients works, because it's configured to manage X clients and there're X processes runing into de OS. 2. We watched that we had X established connections too. At this point everything looks fine, but there are a few strange things... 3. The connection among reverse proxy and apaches didn't carry data, just ACKs. Why isn't TimeOut rejecting this connections? 4. In order to verify who's working bad Apache or Proxies (Although the haven't been cahnged during the update), we inserted a rule into the firewall rejecting any input packet to the webserver. Result: connections became closed, but only after 45 minutes (and our TimeOut is configured in 120 seconds...!) 5. Once connections closed, we hoped that processes should be removed, and the server will start to accept new incoming requests. Not as expected, the server is still "hanged-up".
