How much memory do the SPARC boxen have?

Did you build the client with the God-awful Compiler Collection or the 
Sun Studio/Workbench compiler?

What options did you use to build?

What NIC(s) are on the SPARC boxen?

Does "netstat" report any errors?  On either end?

The box you used in your post is Solaris 8 - are you using UFS or LVM? 
I assume you would be using ZFS for Solaris 10 - lots and lots of RAM 
too, I hope?

Just how full are the disks?

Are the machines busy?

There's not a badly configured switch or something between the clients 
and the servers?  I once had to threaten to drill holes in the walls and 
run our own cabling to a computer room before our incompetent network 
team would admit that "there may be a switch or hub somewhere in the 
chain that is iffy" and unlocked a couple of cable cabinets - oh, look, 
an ancient 10 megabit switch, what a surprise!!!  It wasn't on any of 
the network cabling diagrams, either, no mention of any switches in the 
cable cabinets - as I said, they are incompetent.

Does changing the time at which you run change the duration?  (The old 
"cleaners plug in noisy stuff that is next to the network cable" problem!)

Oh, replace all the network cables from the SPARC boxes where possible, 
that's an easy and sometimes strange one, solid traffic like Bacula can 
show up strange networking problems.

        Cheers,
                Gary    B-)
