FRAG/FRAG2: fragments from X are not cleared if X crashes
---------------------------------------------------------
Key: JGRP-800
URL:
https://jira.jboss.org/jira/browse/JGRP-800
Project: JGroups
Issue Type: Bug
Reporter: Bela Ban
Assignee: Bela Ban
Priority: Critical
Fix For: 2.6.4, 2.7
The reason is that we handle VIEW events only in down(), but since FRAG2 usually sits
somewhere above GMS, we will never get these events !
SOLUTION:
- Handle VIEW in up() as well
- Make sure all fragments from a crashed or left member X are discarded
- Add a JMX operation to manually clear the fragmentation table for X, or for all members
Note that this applies to FRAG as well, but we'll shortly deprecate FRAG anyway
