This may depend where you're getting your information. Specifically, what are you looking at to know that each client backed up or that the savegroup was successful?
There was a problem historically with the TCP Chimney implementation in Windows (*maybe* not Windows specific, but I know for sure it existed there) where saves would complete to media successfully, but during the shutdown of the TCP connections between client and server some packets would not be acknowledged. This resulted in savesets which were complete, successful backups according to DPA (which checks saveset status), but failed backups according to NMC due to a communications error. Depending on your point of reference, all are correct.
There's also a potential discrepancy if you're looking at DPA reports which will show failed savesets which are rerun successfully. Again, it's right that there was a failed saveset, but doesn't easily show that the saveset was also successful.
Thanks guys for the reply. The issue is now fixed.
The problem was with gss authentication for some of the clients in the group. When the server rejected the credential it causing the group failed. Fixed the issue by clearing peer information on both server and clients side.

Hi Iman,
What build of 8.2 SP3 did you upgrade? I would recommend go with the latest cumulative 8.2.3.2 build 1121. It may help you get past this error.
Regards,

Java is not involved with the process just with the visual presentation of the result.
Of course you can go though all the logs but I think you better start with more verbosity.
May I suggest you run the group from the command line using this command:
savegrp -v -G
This should tell you more.

Hello,
First of all there should be any issue with java incompatibility.
But to troubleshoot the you might have to investigate more and need to find out belwo concern -
savegrp -vvv -D9 savegroup_name > /tmp/savgrp.log
