nbatd is failing to start

Hi.

I'm running NB 7.6.0.3 on Solaris 11 x86 OS.

When I restart NetBackup nbatd silently dies. In my messages log I see "Dec  9 10:27:48 wayback nbatd[17474]: [ID 702911 user.error] V-18-24591 Broker has mismatched keypair".

Searching the net, this forum and the documentation I cannot find any way to fix/regenerate these key pairs.

Any ideas or is this a job for symantec support?

This is not an emergency, my backups are running fine. I'm just trying to set up a trusted relationship with another master server.

Thanks!

David
