Bug#486629: apache2 refusing to restart
Hi Stefan, It was already set to 4, I read in the script it something about increasing it to atleast 12, So to be on the safe side I increased it to 30. That makes it take abit longer to restart but thats a better solution than forcing it to stop and then having to reboot to clean things up. Thanking you for your assistance, Paul.

If this is your problem, then apache should die some time after an unsuccessful restart. In this case, you could try to increase the wait time in the init script (there is a t=4 in there, try to increase it to 10 or however long it takes apache to die in your setup). Does this help? If yes, what wait time works for you? Cheers, Stefan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

The init script uses graceful-stop, i.e. the currently active requests will be finished before the apache processes are shut down. But this should not cause the listening sockets to be unavailable. If you use mod_php and your php scripts are executing other programs, you are likely seeing this bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=366124 You can use lsof or "netstat -tlnp" (as root) to determine which processes keep the listening sockets open.

Bug#486629: apache2 refusing to restart
My apologies for the brief bug, it was sent after a 13 hour day at work. Some times I have noticed the system is abit sluggish when I restart apache, the main problem is with apache, it creates lots of child processes that refuse to die, the biggest problem is it then locks up the ports it is using and the only way to kill apache properly at the moment is to restart the whole system. When apache is working it is stable, its been happening for awhile and I was hoping it would have been fixed during the normal update sequence.
