Hello all, (I hope the dev list is the right place for this . . . )
Maybe someone's seen this before: [we're running Lenya 1.2.4, cocoon
2.1.7, redhat 9, jdk 1.5 with Tomcat 5.5 restarted every night]
Once in a while (every month or two) CPU usage goes nuts, java heap
size is overrun, and Lenya dies. When writing to the live cache just
before it dies, lenya throws:
40849730 2006-11-06 15:25:12,870 [TP-Processor610] ERROR
core.xslt-processor.fatalError():81 - Error in TraxTransformer:

java.lang.RuntimeException: java.util.ConcurrentModificationException:
File
/usr/local/lenya/lenya/pubs/academic_affairs/work/cache/live/oaa.html
is already being written by another thread
A few times a second, then CPU usage goes bonkers, then the following:
40912774 2006-11-06 15:26:15,914 [TP-Processor646] ERROR
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/cns].[Cocoon].invoke():253

sitemap.release():188 - Unabled to release processing component.
org.apache.cocoon.ProcessingException: Unable to remove component from
automatic release: no environment available.
At that point Lenya stops responding, and we have to forcibly kill
tomcat (kill -9), and restart it.
It hums along fine for a month or so, sometimes two, then does it
again. Usually it's smooth as glass, with very lo CPU usage.
Anyone seen this before? Currently hunting anything I can f ind on
Cocoon's <map:transform type="write-source">, which is writing to the
cache, as per lenya's default publication set up. Think I'm looking
in the right place?
I am not sure. It might also be one of the "Cocoon cache stores" having
a problem
resp. getting into strange state, but this is just a wild guess.
Have you tried to comment the write-source transformer and see if your
problem still occurs?

Thanks for anyone's ideas about this.
