I haven't used Cocoon2 for about three months, and for the first time I need to
generate a PDF file with data retrieved using SQL. My question is related to memory
usage when using large xml structures.
I generated a xml file using XSP and the ESQL stylesheets (a table with 1336 records)
in order to try to isolate the problem source, this static file was saved and I copied
it multiple times with diferent names to my web application in order to transform them
with a XSL styleshhet to the XSL:FO namespace (a simple table with 3 columns), and
serialized it with "fopdf"
This is the sitemap fragment used:
<map:match pattern="*.pdf">
<map:generate src="{1}.xml"/>
<map:transform src="stylesheets/prr2fo.xsl"/>
<map:serialize type="fo2pdf"/>
</map:match>
I replaced the pipelines in cocoon.xconf with the NonCaching alternatives. When i
access the first pdf file, it is generated and the heap grow to about 60Mb of RAM,
when I access another one it grows near 40Mb, and it continues to grow with each new
pdf request. The free JVM memory always remains low (around 10 or 15 Mb) so the memory
is not reclaimed with garbage collection.
I don't know what may be causing my problem, but if I'm not using caching pipelines,
this Cocoon2 behavior is not normal.
Note: I'm using Cocoon2rc1
Thanks in advance
