[Zope] Increasing ulimit

[Marc Burgauer]

Hi

On a busy Zope instance, we're getting increasingly more often errors of
"too many files open". I already added a line in the start script for that
instance to increase the ulimit to 1024 (the maximum for the machine by
default). 

I am now considering increasing the maximum for that machine to 2048 (or
higher), but wanted to know if other people have experimented with this
before and what risks/dangers I should be aware of doing this.

Here's what my start script looks at the moment (simplified):

> ulimit -n 1024
> python /customer_dir/customer_one/z2.py -X -a212.96.140.5 -w80

This is Zope 2.4 on a Solaris (Intel) box.

Cheers

Marc
