Jean-Frederic Clere commented on MODCLUSTER-120:
------------------------------------------------
it takes a while to reproduce but it is linked with the kill -9 you use in the script.
the shared memory is created but not cleaned, somehow the file of the ftok() is cleaned.
(httpd child processes dectect the death of their father).
The removal fails because the file doesn't exist then new creation (creates the file)
but failed because the shared memory exists in a second run the file exists and the
removal is successful.
Apache with mod_cluster refuses to start at first, after 7 retries it
starts up

Key: MODCLUSTER-120
URL: https://jira.jboss.org/jira/browse/MODCLUSTER-120
Project: mod_cluster
Issue Type: Bug
Affects Versions: 1.0.2.GA
Environment: x64, RHEL 5.2, Server version: Apache/2.2.13 (Unix)
Reporter: Radoslav Husar
Assignee: Jean-Frederic Clere
Priority: Critical
Attachments: MODCLUSTER-120.log
When starting up Apache with mod cluster, by command:
[hudson@perf10 httpd]$ /usr/sbin/apachectl -k start -d /tmp/hudson/httpd
It refuses to start, but creates files in logs one-by-one and then when all files are
created it accepts to start.
[hudson@perf10 httpd]$ cat logs/error_log

The configuration is here:

Is there a workaround? What might be causing this?
