Running: Cocoon 2.1.5; Tomcat/4.1.29; Java 1.4.2; WindowsXP
I keep bumping my head into memory problems with *some*
Cocoon operations. See the log snippet below - I am trying to
serialize a SVG file to JPEG -> the process works fine when
the file sizes are from 1-250k. As files gets larger (300-500k),
I eventually get the dreaded java.lang.OutOfMemoryError message
in the Tomcat server log. In fact, in some cases Cocoon *can*
process the larger file, but as soon as I hit 'refresh' the memory
overflows.
If I use the Windows task Manager; it seems that Tomcat is not
using more than about 132MB... the settings for Java *should* allow
it to use up to 256MB... ie. CATALINA_OPTS is set to:
-Xms64m -Xmx256m -Dfile.encoding=ISO-8859-1 -DproxySet=true
-DproxyPort=3128
When I run other processes through Cocoon e.g. some of the samples
then the memory usage can hit about 147MB.
Any assistance with this is gratefully appreciated.
Thanks
Derek
PS I am not sure this is related, but I get similar problems when
working with the directory generator
<map:generate src="dir" type="directory" include="*.xml"/>
after some random number of refreshes, this operation, too, causes a
memory problem.
