Baptiste MATHUS commented on MODCLUSTER-120:
--------------------------------------------
I'm having the same problem. After some analysis, I don't think this problem is
related to shared memory or so.
I think it's only related to right management, as stated in the first comment. I
thinks the fact that it's able to start the seventh time (which I can't reproduce)
is related to some particular config or case.
More precisely, I think it's related to the fact that httpd typically starts itself as
root since it must commonly be able to bind on <1024. Once done, it immediately changes
user to another one (commonly "apache").
I guess the manager.node is created by the corresponding module before changing execution
user. Then, after user change, as "apache" user isn't root, it gives the
error saying it's not able to access the previously created file.
On a related note, I'm wondering: is there a way to know the version of an installed
mod_xxx_.so with some command?
Thanks a lot.
PS :
RHEL platform, (official rpms I seem to remember), and using the modules coming from
JBoss5.1-EAP DVD.
Apache with mod_cluster refuses to start at first, after 7 retries it
starts up

Key: MODCLUSTER-120
URL:
https://jira.jboss.org/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
Fix For: 1.1.0.CR1
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

Is there a workaround? What might be causing this?
