PLEASE upgrade your appliance as a matter of urgency to match master server software (2.7.3).
Other than support from Veritas, you also get new features and bug fixes.
When the appliance is at a supported level and the issue persists, you can log a call with Veritas support to investigate.
Yes we are recommending our management for the same, but a date is not yet fixed as the upgrade involves cost, also few weeks back we got a maintenance window to perform the upgrade but we couldn't even initiate the upgrade, as when we rebooted the appliance, it reported CRC errors , then the MSDP pool was showing down on master server, later the DNS cache was cleared and the pool was up, so we arent sure if the CRC errors till persists on the pool, if so it will not allow to perform the upgrade.
Until then management is saying to find a temporary fix/workaround.
:(
The problem with the unsupported Appliance is that you are going to find it very difficult to find a temporary fix or workaround.
Members on this forum have suggested a few things to the best of our abilities.
If none of that has helped, you are really on your own.
You may want to show your management this discussion.
PS
I'm not sure why you believe that upgrade involves cost.
The fact that your master is on a currently supported NBU version should entitle you to free upgrades that includes the Appliance software.
With active support, Veritas Support will be able to assist with the upgrade and look at issues that might prevent successful upgrade.
Simply log the call as 'upgrade assistance'.
