NetBackup 7.7.2 stops responding

I have this problem where my master server stops responding after about 5 days. please note that its the nbu that stops responding but there OS runs fine. restarting nbu services works but i dont want to keep on restarting services every week.

OS version: SuSE 12.

NBU Version 7.7.2

when i try to log on it only stops at the stage: Connecting Netbackup service layer. when this happens i get a lot of bpdbm processes (more than 20) running on the server. Normal operation its only 3 or 4 bpdbm processes.

i am running backups to quantum dxi using OST and replicating to DR on this environment.

what do i need to check when netbackup stops responding?

    Hi Ngarart,

    I would ask typical questions: 

    * Is this a new setup?

    * If not, anything changed prior to it happening? e.g. upgraded from version x.x.x.x to 7.7.2, added Oracle policy etc.

    * What's the output of /usr/openv/netbackup/bin/bpps -x? Any critical processes missing?

    * Check what the bpdbm and nbsl logs say, they are in /usr/openv/netbackup/logs/bpdbm/ and /usr/openv/logs/nbsl/ respectively.

    * Have you tuned the master server ? https://www.veritas.com/support/en_US/article.TECH167095 is a good start.

    What does /var/log/messages say ?

    Have you run the SORT collecttor to see if OS has the right kernel settings :

    See the "Custom Reports Using Data Collectors".

    Hi Wiriadi

    This is a new setup less than two months old. Nothing changed.
    I have updated  /etc/security/limits.conf values as recommended.
    I also did add  fs.file-max = 2097152 in /etc/sysctl.conf. Without that i was getting Too many open files in system error.
    Now I will have to wait for about 5 days to see if this is going to happen again.
