[jboss-jira] [JBoss JIRA] Commented: (JGRP-678) NPE in NAKACK under startup load
[ http://jira.jboss.com/jira/browse/JGRP-678?page=comments#action_12398251 ]
Bela Ban commented on JGRP-678:
-------------------------------
This needs to be reproduced (with WARN level set for all of JGroups). Then grep the logs
for:
- " from xmit_table (not member anymore)"
- ") from xmit_table, received incorrect new membership of "
- "digest does not contain local address (local_addr="
I changed the adjustReceivers() method such that local_addr is *never* removed from
xmit_table, dito for setDigest()
NPE in NAKACK under startup load
--------------------------------
Key: JGRP-678
URL: http://jira.jboss.com/jira/browse/JGRP-678
Project: JGroups
Issue Type: Bug
Reporter: Bela Ban
Assigned To: Bela Ban
Fix For: 2.7, 2.6.2
Attachments: NAKACK.patch.txt, NAKACK.stack.txt, peerProtocolConfig.xml
Here's another NPE that we found, this time in NAKACK in 2.6.1. Again, we
are starting up ~30 systems at once which causes some thrashing for a couple
of minutes until things settle down.
You will notice that we also moved over to trace the dumping of the NAKACK
table which at some points threatened to overwhelm our log systems. That
has (I think) been mentioned here before.
