Today i was working on SA for packet, the appliance shipped with 10.3, after few round testing, some issues made us decided to roll back 10.2 SP2, below are the issues:
1. Malware cloud(community) not able to activate, roll back 10.2 SP2(with same CID) resolved issue.
2. Broker missing meta value. The new index-broker.xml only has one entry regarding time. From the testing, malware not able to get any files to analyse. If target to concentration, everything works. Roll back to 10.2 SP2 resolved issue.
I searched KB, so far no 10.3 issues yet. maybe need to wait 10.3 SP1.
The reason index-broker.xml only has time is that it is no longer necessary to update the index on a broker. It gathers it's language from all the downstream devices. So it the broker talks to 3 concentrators, it will make the language call to the 3 concentrators and merge the results. It is only necessary to maintain the language on the concentrators.
However, if you feel it necessary, you are welcome to define a language in index-broker-custom.xml. That will be used if it's provided. The only time that would be necessary is if all devices are offline and you still want a full language returned.
