Robb,

Yep, that patch solved the pqact problem.  I'm running 5.0.8 now, I'll
let you know of any further problems.

As for the large queue/swapping problem, I'm running kernel version
2.0.35 on a dual pII machine, with the rest of the operating system
being RedHat 5.1. I'm looking around to see if there are any kernel
changes in the more recent 2.0 or 2.2 series that address large memory
mapped files, or memory management in general. 

I believe that memory management in general is better in the 2.2
kernels, and there are also optimizations for newer processors (i.e.
Ppro, PII, etc) that take advantage of the newer architecture and speed
things up alot too, so I may try upgrading that machine to RH 5.2 or 6.0
and the 2.2 series of kernel.

If I find anything out, or have any successes or failures in all of
this, I'll forward the info along to you.

On the SGI IRIX 6.5 front, my queue has grown from the 120 Mb I set it
to (up to about 140 and leveled off). I'm not filtering the NOAAPort
stream at all, so that probably accounts for the large queue necessity.
It hasn't crashed since yesterday though (fingers crossed) so it looks
like the large queue size is the fix for that.

Thanks again for all your help!  Sorry to hit you with all these
questions/problems all at once, but now the semester is pretty much
over, and I've got a little time to look into these little nagging
problems.

Pete
