Subject RE: Memory problems with Cocoon
Date Fri, 17 Sep 2004 20:23:38 GMT

We have had similar issues as well. The first thing I would check is to see
what type of pipeline configuration you are running with. If you are running
w/ profiling turned on we have found that the profiler slowly eats up all of
our memory over time. I work for a publishing house and we have some very
large documents being fed through the pipelines so running w/ profiling
turned on hasn't been a viable option for us anywhere but in our local

Even w/ profiling turned off however w/ just caching enabled the server
seems to slow down over time and run out of memory until we have to reboot
it. Seems like there could be a leak somewhere ... but i wanted to play
around w/ the store heap settings some before I can really be sure of that.
I'm thinking the heap could be filling up and there is not enough free
application memory to transform some of the bigger documents???

Anyway, I'd love to compare notes on performance tuning Cocoon.

BTW - We are running w/:

Cocoon 2.1.4
Java 1.4.2

Cheers, Greg

Subject: Memory problems with Cocoon

All, I followed the Wiki docs for Performance issues with Cocoon, 
Lenya, etc., and I'm watching my server now and the free memory is 
slowly going away, until the log file starts spitting out the following 

Cocoon threw exception

I don't know if this is the proper place to post this question, but I'm 
hoping someone has experienced the same and has some tips or help on 
this one.  I have the following software running:

Cocoon 2.1.5
Lenya 1.2
Java 1.4.2_04

I ran through the Wiki doc on performance to get myself going.  Anyone 
have anything that can help me track this down?  You'll be highly 
praised for your help.  :)
