Hi all,

I have been working with legato support for the past month or so with no
luck so I am going to see if anyone else has seen this.  First here is my
enviroment...

Networker 7.1.1 running on AIX 5.1
An IBM3583 Library with 4 LTO-2 Tape Drives attached via Fibre and across
the SAN

The jukebox parrellism is set to 4

What I am seeing is that if 3 or more nsrjb commands are kicked off to load
tapes nothing happens.  The nsrjb commands just hangs and no tapes get
loaded.  The nsrjb commands cannot be killed, I have tried shutting down
networker and removing everything in /nsr/tmp but I still cannot kill the
nsrjb commands (even with kill -9).  The only way to get rid of them is by
rebooting the server.

Has anyone seen anything like this?

Also, I am not getting any errors on the library or the tape drives as long
as there are only 2 nsrjb commands running at a time everything seems to
work.

One last thing, legato had me change the jukebox parrellism to 2 saying
that by doing this it would limit legato to only running two nsrjb commands
but even after changing it, legato kicked off 4 nsrjb commands and hung
once the backup started.  Does anyone know what the jukebox parrellism
actually does?

Thanks for your help.
