NW 7.4.5.1. on Win2003. The server is Win2003 Standard, 4G RAM.

My server has gotten increasingly unresponsive when processing jobs. For 
example, when I have 3 cloning jobs running (no saves; just cloning from 
AFTD devices), moving from MONITORING to DEVICES in the NMC gives me the 
"connecting to server" msg, and a few seconds wait. Sometimes longer. And 
I've now sometimes also seen "Server does not respond to UDP ping", and 
jobs failing, as well. I've had client backups fail with RPC errors. 
Reboot the NW server, and everything works exactly as it should. For a 
while ...

I'm looking throught the 7.4 Performance Tuning Guide now. Any immediate 
suggestions?

I upgraded from 7.4.2 (where this problem of slow NMC response was 
starting to manifest itself) to 7.4.5. A few days after that, I also 
upgraded the hardware (I had 2 libraries, each FC, but each tape drive was 
not individually fiber connected. I removed 1 library; removed the 4 
SDLT-600 drives from the remaining library, and replaced with 8 FC 
connected LTO-4 drives). So now I have 1 library, with 8 fiber connected 
LTO-4 drives.

Since the hardware upgrade, the problem has only gotten worse.

Thoughts? Suggestions? Specific areas to look at?
