Hi,
I am trying to generate a large response (>500MB) from a pipeline but get out
of memory errors. I cannot just increase the jvm memory as the response may
be of arbitrary length. I have tried to configure a pipeline that streams
without caching or creating an in-memory tree using the following sitemap
fragment:
<!-- cocoon 2.1.6, jdk 1.4.2_05, tomcat 5.5.4 -->
<map:pipeline type="noncaching">
<map:parameter name="outputBufferSize" value="8192"/>
<map:match pattern="imp-muze-pop-2-sql">
<map:generate type="serverpages" src="xsp/imp-muze-pop.xsp" label="1" />
<map:transform type="stx" src="stx/test.stx" label="2" />
<map:serialize type="text"/>
</map:match>
</map:pipeline>
This does seem to stream as I can see the output however the jvm memory
allocation continues to grow along with the output. Is there a way to see
which component is holding on to memory?
Hey, Joel!
(Ugh, I am fighting "out of memory" errors today too, as it just so
happens... but not from Cocoon) Anyway... this might be dumb, but...
if you remove the STX transformer and then hit the pipeline, e.g. using
"curl -O http://where.ev.ver > /dev/null", then you could see if it's
that component, right?
Best Regards,
Mark
