socket: no buffer space available

[Andrew Thomson]

I've got a perl script doing some p5-sybase stuff for me.. However after
a while, it fails with the following error message:

.."socket: No buffer space available"...

I've seen other reports from other uses getting this problem however no
clear responses on a fix.

This script used to work find on my 5.0-RELEASE box now I'm trying it on
a 5.1-RELEASE box. I admit the new box is a lower spec - less cpu and
less memory - so that may affect some of the default sysctl values???

I've tried tweaking a couple of sysctl entries however nothing has
gotten me over this hurdle.

Below are some relevant(??) sysctls.

kern.ipc.maxsockbuf: 1048576
kern.ipc.sockbuf_waste_factor: 8
kern.ipc.nmbufs: 17920
kern.ipc.nsfbufs: 2496
kern.ipc.mbuf_wait: 64
kern.ipc.mbuf_hiwm: 512
kern.ipc.mbuf_lowm: 128

kern.ipc.numopensockets: 94
kern.ipc.maxsockets: 4008

Any suggested tweaks appreciated.
