idle httpd childs consuming 100% cpu

           Summary: idle httpd childs consuming 100% cpu
           Product: Apache httpd-1.3
           Version: 1.3.27
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: core
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: fluke@krneki.org


A few of httpd childs hit 99% cpu load and they don't exit ever until I manually
kill them (or run apachectl restart).
By comparing PIDs, server-status reports apache is sending reply, however tcp
connection with an IP (which requested url) is closed long ago.

This is very annoying since httpd childs starts accumulating, and over a few
hours/days period server hits very high load (40+).

Right now I have "apachectl restart" in my crontab every few hours, but that's
not really the solution I want.
Perhaps there's a way of forcefully killing a child after 30 minutes, or after
it consumes certain amount of cpu time.
I'm using apache 1.3.27 with php 4.3.1.

I tested apache 2.0.45 (+php 4.3.1) and it seems it handles this kind of lockups
somewhat better, most high cpu childs die, but some still stay running.
