The next wrinkle is that I'm now getting:

2010/11/22 08:49:52.715 1       ProxyChannel.cxx(4655)  Q931d   Could
not open/connect Q.931 socket at 38.124.39.252:30093 - error 7/24: Too
many open files
2010/11/22 08:49:52.715 3       ProxyChannel.cxx(4325)  Q931
200.251.250.14:1720 DIDN'T ACCEPT THE CALL

If I increase the ulimit -n to 20000 I get:
2010/11/22 08:55:52.470 0       ProxyChannel.cxx(7051)  Proxy   Too
many opened file handles, skipping handle #1024 (limit=1024)

I've read the docs and I'm still not sure if the large fd_set portion applies.

I'll be happy to add something to the documentation once I get an idea
of what's going wrong. :)

I've checked in google and there's various information, but nothing in
one place.

Here are the changes that I've made so far:  (Ubuntu 10.04.1 LTS)

Updated /etc/security/limits.conf

*                soft    core            unlimited
#root            hard    core            100000
#*               hard    rss             10000
#@student        hard    nproc           20
#@faculty        soft    nproc           20
#@faculty        hard    nproc           50
#ftp             hard    nproc           0
#ftp             -       chroot          /ftp
#@student        -       maxlogins       4

*                hard   nofile          32768
administrator    soft   nofile          32768

If anyone else is running large-scale GnuGK installations then I'm
eager to hear what changes you made to make this operational...
