hi,
when high loads, the cocoon server display Error in free() in the log file
and loop, then java threads grows and freeze.
Tomcat must be stop (kill -9) and relaunched (every 1/2 days).
2 processors, 1Go ram machine
Red Hat 7.3
tomcat 4.0.1
java 1.3.1_10 (-Xms64m -Xss64k -Xmx256m )
very old cocoon release 2.x (don't know where the release is located)
postgresql (lastest version)
Any idea ? do i upgrade the java, cocoon, tomcat application; it seem to
come from the MRUMemory managing process ? i didn't see a bug like this in
forums, web search
My client is ready to pay an french cocoon expert need Paris.
We must solve this very disastrous error, i never had this error before on
an older Red Hat release.
Thank you for your help, ideas...
Patrick
I try any parameter in cocoon.xconf, even deactivating the filesystem value
<store class="org.apache.cocoon.components.store.MRUMemoryStore"
logger="root.store">
<parameter name="freememory" value="1000000"/>
<parameter name="heapsize" value="40000000"/>
<parameter name="cleanupthreadinterval" value="10"/>
<parameter name="maxobjects" value="100"/>
<parameter name="usecleanupthread" value="true"/>
<parameter name="threadpriority" value="5"/>
<parameter name="filesystem" value="no"/>
</store>
[root.sto] (): Error in free()
