Error 0 General Ping of nbjm failed, communication lost

[Gerald_W__Gitau]

Hi everyone,

I have got this problem now on its 3rd debut "General ping of nbjm failed, communication lost". It happens just after midnight when Full backups are running or about to run. The jobs that were already running hung, and other jobs that are supposed to run do not kick off. I have on previous occassion extracted nbsupport logs and sent them to Veritas but no satisfactory answer as to why it happens, what causes it and how to prevent it. Anybody who has experienced this??

NBU ver 6.0 MP4

Servers - WK3 STD Edition SP1

Clients - Mixed WK2, W3K, Unix, Linux

Note: Removal Storage Service has been disabled on master and media servers. The problem has never happened when only incrementals backups are running!!

to fix this you will need post MP4 Binaries from backline engineering. I had the same problems with jobs ending with a status 50.

And let me know if this helps!
