[Veritas-bu] Long time between "requesting resources" and "granting reso

Hi all,

I'm seeing some apparently slow backups.  When I dig into the job
details, I see that often there's a long delay between the "requesting
resources" messages and the "granting resources" messages.  

The master server is an 8 CPU, 16G Solaris 8 v880 box.  It's got
NBv6.5.1.

It's running with an average of 50% idle or so but the load average is
kinda high: 


last pid:  8851;  load averages:  4.01,  3.66,  3.60
11:50:46
170 processes: 164 sleeping, 1 zombie, 1 stopped, 4 on cpu
CPU states: 53.2% idle, 13.0% user, 28.8% kernel,  5.0% iowait,  0.0%
swap
Memory: 16G real, 8702M free, 2372M swap in use, 24G swap free



Here's the details of a job that ran slower than I'd like.  36 minutes
from "request" to "granted".  It's a high-priority backup, highest of
all of them, FWIW.  It, and many of my policies now, are backing up to
storage unit groups.   The AP-01 client below is an AIX media server
with NBv6.

Anybody seeing this?  Any reasons you know of?
