Netbackup gets extremely slow after a few days

[jacopieterse]

Hi,

I'm running Netbackup 7.0 for Solaris Sparc on a SUN v215 server. I've got a fibre connected SL500 with 4 LTO3 drives.

After a few days to a week the whole environment will start to slowdown to an almost halt. It will start with Error 25, 37 and 811. If I do a netbackup stop and start it does solve the problem for a few days. Now what I do before my full backup cycle over the weekend I restart the server and the Robot and then it will work fine.

Can someone please point me in the right direction? The problem basically started since the upgrade to Netbackup 7.0. I also have a wide variety of clients: Solaris X86, Sparc, Windows 2Kxx etc.

Thanx in advance.

(e.g. master/media) after you've restarted for any "extra" processes that may be building up over time or that start to utilise more resources e.g. memory/processor?

Get to know what's there normally & the resources used & then compare that with when you start to get issues?

Hi,

Did you follow any of the tuning recommandations for the Solaris kernel when used with NBU?

The symptoms sound like a result of lack of tuning.

Also you could do a check for sockets in TIME_WAITING status
'netstat -na|grep -i time'

Many (more than 10-20) sockets in this state could point in the direction of need for tuning of the network settings as well
