Hi Guys
I am running NetWorker 7.4.2 on a Windows 2003 SP1 server, backing
up to a STK L180 library with 3 tape drives.
The backups seem to hang everynight on the following message:
nsrjobd Jobs error: Unable to find record for job 32327 during an
attempt to send message to it.
From the daemon.log i can see the following messages appear before
the one above:
4154 10/06/2008 20:36:52 nsrmmd#1 Lost connection to Media Database

I have engaged EMC on the matter, but so far they havent been able
to pin point the cause of the problem.
So far I have done the following:
stopped NW services and renamed the /nsr/tmp and /nsr/res/jobsdb
directories.
looked through DNS and /etc/hosts for erraneous entries
Disabled strong authentication
Reduced savegroup parallelism (in case server was overworked)
Reduced server parallelism (in case server was overworked)
Also it is worth knowing that Antivirus does not run at that time.
All NIC and switch ports are set to 1GB full duplex.
All NIC and Teaming software is running on the latest HP drivers
I feel like I have exhausted all avenues.
Does anyone have any ideas or is suffering from the same issues?
Do you still see the same problem with nsrjobd after you made the
changes you mentioned? If so, you might have to do some TCP/IP tuning.
I am not that skilled with Windows, but I had a similar problem with
Solaris 10 and NetWorker 7.4 and I saw much improvement by making
certain adjustments to some of my server's TCP/IP parameters. You
might try asking EMC for recommendations or perhaps someone else on
this list can provide recommendations for TCP/IP tuning in a Windows
environment.
Also, what kind of server are you using for NetWorker (processor
speed, amount of memory, disk space)? Does this problem happen
frequently? What is the load like when this happens?
