too many open files
hi,
from time to time my cocoon get this error message:
Too Many Open Files
Sometimes after refresh it continues work, but sometimes it needs to be
restarted.
Is there any way to fix this issue?

Impossible to say, it all depends on how the replies to these hits are
generated, and your traffic patterns. You need to measure the
performance with simulated or actual load to make decisions about
this.
10'000 hits a day (86'400 seconds) can be as low as 0.12 per second if
evenly spread, which is not much at all. OTOH if these hits come
within 2 minutes...you get the idea.

Not that I know, quite the contrary, except that it cannot listen on
port 80 then. But it's a good idea to put an httpd / reverse proxy in
front anyway.

How high should be "very high load"? over 10 000 hits a day?
Are there any drawbacks running cocoon as non privileged user?

Not necessarily, it's not optimized for very high loads but runs just
fine on several of my production systems, with up to 9 months uptime
until now.

As a matter of a fact I'm not using cocoon with combination with tomcat,
should I? Are there any drawbacks if I use it alone with the standard
bundled server?

And i would add: running with Tomcat under Linux with a non-privileged user?
(see /etc/security/limits.conf)

The question is, what are your application patterns, i.e. do you use
many XSLT transforms, or the SQLTransformer, often call external
processes, use a lot of Flow and/or CForms, etc..

No special components, just cocoon started with
cocoon servlet.
What do you mean by "what kind of app is this?"

We need more info to help, what kind of app is this, what components
of Cocoon and what external components are you using?

Which might be: using the Process object and not explicitely closing
its channels, see http://codeconsult.ch/bertrand/archives/000456.html

I heard something about a Java bug that seemed to cause these kinds of
errors. What version of Java are you using and what happens if you
update to the latest version (if you are not yet using it?)
Kind regards,
Geert
