           Summary: Apache 2.0.42 hangs on AIX 5.2
           Product: Apache httpd-2.0
           Version: 2.0.42
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: critical
          Priority: P2
         Component: worker
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: bruce.nolan@pbsg.com


I read through some other bug notes (#9011), but did not see a fix for this 
problem in versions 2.0.43 - 2.0.58 or whether this fix is still in dev.

Apache will stop responding to request after a couple of hours.  I'm running 4 
different/seperate Apache binary installations on this hardware, all running 
on individually unique (sometimes multiple) IP addressess under unique install 
locations.  The hanging server is isolated to one install location and is this 
same one that stops everytime. All other running servers continue to run fine. 
A graceful or full restart using apachectl clears up the problem.  Please see 
following for compile options and log file entries:
