Hello,
The TCP tuning parameter have been mentioned for Unix\Linux\Aix servers 
here at the list in the past, if someone can re-post or search through, 
they can easily be adapted for windows, usually, via editing registry &\or 
NIC driver properties.
Thanks

[Networker] nsrjobd Jobs error:






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? 

Hi Stan thanks for the reply.

I havent tried any TCP/IP tuning yet, maybe someone can help on this??

Also the server we are using is  a proliant DL580 G2 with 4 CPUS 2794mhz
3.8 GB RAM
1.2GB Virtual memory
9.67GB page file.

The funny thing is that we have 2 NetWorker Datazones that are mirrored, 
both NetWorker servers are identical, However at 20:30 everynight when the 
"biggest savegroups" start (60 clients each).  Both servers start to throw 
up the following errors:

nsrjobd Jobs error: Unable to find record for job 32327 during an 
attempt to send message to it. 
4154 10/06/2008 20:36:52 nsrmmd#1 Lost connection to Media Database

(nsrjobd) 
32490 10/06/2008 20:36:59 savegrp group Live-Exchange-Daily aborted. 

I think from e resource point of view we have plenty spare, however 
something seems to be bombing out the server and I cant quite put my 
finger on it.
