-------------------------------------
Thanks Jean-Frederic for the update. Do you mean ThreadsPerChild was not set properly? If
so, what is the recommended way to calculate a proper value?
May I know more details of how this config would cause the problem. So we could explain it
to customer accordingly.
I will also ask customer why they need PersistSlots On. Will get back to you.
When setting PersistSlots to On, EAP node can not rejoin mod_cluster
due to java.lang.IllegalArgumentException

Key: MODCLUSTER-636
URL:
https://issues.jboss.org/browse/MODCLUSTER-636
Project: mod_cluster
Issue Type: Bug
Components: Native (httpd modules)
Affects Versions: 1.3.5.Final
Environment: * JBCS httpd 2.4.23 SP2
* mod_cluster: 1.3.5
* EAP: 7.0.8
Reporter: Alex Cai
Assignee: Jean-Frederic Clere
Customer set 'PersistSlots On' and sometimes the jboss eap node could not rejoing
into mod_cluster due to java.lang.IllegalArgumentException
When they got this exception, they have to delete every cache files then restart httpd
and jboss for join correctly.
Customer tried the below actions:
1) apache stop -> delet manager.* files in the mod_cluster directory -> apache
start
- this action could cause http 503 error
or
2) pre-backup the all files(normal files before issue) in the mod_cluster directory. when
the issue occure, apache stop -> restore manager.* files from backuped files ->
apache start
- no http 503 error
Please see the case for more details:
