DESCRIPTION:
EX SSL-VPN: Policy Replication fails on 10.6.3

RESOLUTION:

Problem Description:

Policy replication fails with high number of ACL rules and resources.

Post upgrade to 10.6.3 when we replicate the master says replication failed. On the recipients it logs a successful replication but the changes are left as pending and don't apply.
Also we get Java errors in AMC console until we restart mgmt-server.

Resolution/Workaround:

Tracking ID DTS #137424

SonicWall engineering fixed the issue with a workaround (Hand edit) along with a test hotfix. Please contact Technical support for the test-hotfix.

Root cause of the problem is JVM Out Of Memory during replication. To increase the memory allocation, please do the following on BOTH sender and receiver(s) nodes:

1. edit /usr/local/app/mgmt-server/bin/start.sh (line 107: add -Xmx512m after $JAVA_HOME/bin/java)
(start.sh attached)
2. #/etc/init.d/mgmt-server/restart
3. Try replicate, we should be able to replicate successfully.

Note: This is officially fixed in 10.6.5 and 10.7.1 already
