Subject Re: instability of cocoon image reader?
Date Fri, 05 Dec 2003 19:35:03 GMT

I'm running cocoon in a tomcat 5 caontainer using the default startup 
I'm not shure how much heap this is by default.

It seems the tomcat java process requires 113 mb right now.
Im running cocoon 2.1.3, tomcat 5, redhat 9.
