           Summary: Segmentation violation in httpd - thread/worker
           Product: Apache httpd-2
           Version: 2.0.59
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: critical
          Priority: P2
         Component: worker
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: thulek@cz.ibm.com


We suffer from SIGSEGV abnormal httpd terminations. It seems to be related to
the worker/thread components.

The crashes only happen under higher load, on AIX 5.3.

More detailed info:
--------------------------------------------------------------------------------------------------------------
We run the same binary on more than 200 servers with AIX 5.2 without problems.
We have reproduced the problem with '-g' compiled binary:

ts9 /work/thulek/httpd-2.0.59/server# dbx /usr/adissys/httpd/bin/httpd
/usr/adissys/httpd/core
Type 'help' for help.
