      Description

      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
