Hi Everybody:

I have Netbackup 3.2 patch 363 on a HP-UX c3000 server with DTL7000 Drives. 

We were getting really slow restore times on restores that were > 1GB
Averaging speeds were around 1/4 GB/H
Tech support and myself looked at the logs and found the restore would run
and then pause for a while and then run again. I was told this is because it
is running out of system resources and instead of reporting an error it is
just waiting for them to free up. I was given a list of Kernel params to
tweak, but they were for Sun Solaris. I found the equivalents in HP and
tweaked them. The performance when up to around 2 GB/H. 

I still see the pauses in the restore log file, they aren't as long of a
pause but they are still there. I greped all logs for errors and the only
ones I found are from bpsched and bprd. 

bprd/log.033000:08:41:25 [11184] <2> recv_msgQ: msgrcv(nodelay) stat 20
errno 0 (Error 0).
bpsched/log.033000:00:12:19 [27593] <2> recv_runQ_msg: msgrcv(nodelay) stat
532  errno 0 (Error 0).  sigcld=0 sigalrm=0 sigusr1=0 sigusr2=0

I guess they are from running out of message queues. I want to increase the
tweaks but I don't know which ones, and I don't know if they have to be in
certain increments.

I anyone can give me any insight in to what is going on, any information at
all, like, I should monitor such and such with sar.  I would really
appreciate it..

It's a HP 700 C3000 with 512 MB of RAM and a 1GB Ethernet card.
