I have to confess my ignorance of Spring's framework...I suggest
googling on dbcp and data leaks and you may see if the method is common
to both?

Thanks Paul.
I'm not certain, but it doesn't look like i'm using commons-dbcp.
I think the spring DriverManagerDataSource is replacing it in this case?
Below is what I'm using for my connector:

I vaguely recall having this problem in Cocoon 2.1.11 and that it
seemed to go away when I replaced my commons-dbcp jar with the latest
I could find (commons-dbcp-1.2.2.jar)

Hello,
I wonder if anybody can help me or point me in the right direction.
I get database connection leaks if I'm including pipelines which
reference other pipelines too many times.
I'm using Cocoon 2.2
PostgreSQL 8.3 with postgresql-8.3-605.jdbc3.jar
Here's what I got:
Data comes from the parent sitemap, and the child sitemap uses that
data.
I've tried including the data using map:aggregate, XInclude,
Include, and XSLT/document()... all lead to the leaks one way or
another.
For each of the "bad" piplines, I get a new idle postgres connection
hanging around indefinitely.
Below,
for the via-agg.xml pipeline, the 3rd include does the job. If I
remove that one, then I don't get a leak.
for the via-include.xml pipeline, if I use only one of the "CULPRIT"
includes, everything is fine. But if I use any 2 of the includes,
then I get a leak.
Any ideas?
Thank you very much for your help.
