PBX client communications on NB7.1

PBX constantly has 100+ connections (port 1556) open on the local server even when no backups are running.

The PBX log file shows

    Looks pretty normal to me ...

    Even with no 'jobs' running NBU processes are still talking to each other and it wil be these that create the connections.  The connects don't close instantly, but over a period of time as new ones are appearing , the old ones will be 'dropping' off.

    Checked a couple of machines here - and they are doing the same.

    In summary - it's just how PBX works.

    Are you seeing any issues with NetBackup, if not do not worry about it.

    As mph999 says, it's normal

     

    I have an idle system running absolutely no jobs at the moment, it has 112 PBX connections showing under netstat -a

    are you using any other product like storage foundation 

    b'coz PBX is also responsible for Storage Foundation.

    Yes - the perfomance from clients with such large number of connections to the PBX port are very slow

    Wondered if PBX is too busy ?

    I presume you mean backup performance ?

    What are the clients OS and NBU versions

    The media server OS and NBU version

    The Master OS and NBU version

    If you run a job (if I am correct about backup performance) and send in the bptm log from the media server and the client bpbkar log.

    So, you mention client performnace - is this ...

    All clients or just a few

    Considering these clients, have they always been slow, or has the problem just started

    If the problem has just staarted, what has recently changed

    bpbkar (client) -> bptm (media) does not use PBX, so if the backup is active and slow it has nothing to do with PBX. Following mph999 advice will help here.

    How many clients are affected? All or just some?

    PBX comes into picture only during connection establishment. Once connection is established, the communication is never mediated through PBX. So once connection is established then backup performance would not hit because of PBX.
