Description Aaron Ogburn 2013-07-29 20:09:25 UTC
Description of problem:

mod_manager truncates ENABLE-APP messages since it reads only the first packet.  This can result in / being enabled instead of a given, more specific application context


Version-Release number of selected component (if applicable):

1.2.4.Final

How reproducible:

With test case from MODCLUSTER-349, always.  Less reproducible in actuality.

Steps to Reproduce:
1. Run MODCLUSTER-349 test case

-OR-

1. Set up jboss+mod_cluster for large ENABLE-APP messages (high alias counts) for non root context
2. Check mod_cluster-manager page to see if root was enabled instead of the expected context

Actual results:

mod_cluster doesn't read multiple packets for MCMP, potentially resulting in improper / enables.


Expected results:

mod_cluster does not enable / improperly.  It reads multi packet messages and handles them appropriately.

Comment 1 Aaron Ogburn 2013-08-19 19:16:56 UTC
Fixed in mod_cluster per MODCLUSTER-349.  EAP 6.2.0 needs to use mod_cluster 1.2.5.Final to acquire the fix

Comment 2 Michal Karm Babacek 2013-10-01 13:07:26 UTC
Verified with EAP 6.2.ER3 / mod_cluster 1.2.6.Final.
