------------------------------------------
I notice the same problem as Eric. After transforming a few ten thousend
documents, I get:

> [PATCH] XSLTC resource leak causes 'No more DTM IDs are available' error
> ------------------------------------------------------------------------
>
> Key: XALANJ-2439
> URL: https://issues.apache.org/jira/browse/XALANJ-2439
> Project: XalanJ2
> Issue Type: Bug
> Components: XSLTC
> Affects Versions: The Latest Development Code
> Environment: Linux and Windows XP with Sun JRE 1.5.0_15 and 1.6.0_05
> Reporter: Helge Schulz
> Priority: Minor
> Fix For: The Latest Development Code
>
> Attachments: DOMLeak-4-NodeSetAndMultiDOM.xsl,
> DOMLeak-XSLT-Test-1.0.jar, DOMLeak-Xalan-SVN-r584164.patch
>
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> The Xalan XSLT compiler (XSLTC) has several resource leaks in handling
> result tree fragments in XSLT variables and parameters. If a variable
> or parameter declaration contains XML elements, a new DOM tree is created
> and a new internal integer id is reserved for it. The garbage collector can
> never retrieve this DOM tree, because the id registration holds a reference
> to it. This bug prevents the transformation of large input files, because
> complex templates creates many result tree fragments and exceeds often the
> absolute limit of possible DOM trees in XSLTC (2^16 = 65535). If this
> limit is reached, XSLTC throws the following exception:
> DTMException: No more DTM IDs are available
> The attached patch adds a new release method to the DOM interface and calls
> it, when the scope of a variable or parameter is leaved.
> You can test this patch with the attached JAR file. This file can be
> called with
> java -Xmx800M -jar DOMLeak-XSLT-Test-X.Y.jar
> This file contains four test style sheets with expected output files.
> This bug exists also in *all* Sun JRE 1.5 and 1.6 versions, because the
> Xalan XSLTC source code is used in the 'com.sun.org.apache.xalan.internal'
> packages. The attached test JAR file contains also a patch for the current
> Sun JRE version 1.6.0_5 and a fix JAR file to be installed into the
> '../jre/lib/endorsed' directory of the JRE installation.
> Please add the attached test files to the Xalan test suite. I have
> released them under Apache license version 2.0.
