No more DTM IDs are available?
I am using Cocoon to generate PDF documentation as part of a build
process, as in the Jakarta Avalon project.
Very often, I get a "No more DTM IDs are available" exception (see
complete trace below) and the build fails. This appears to be a Xalan
exception.
However, it does not happen every time. I can find no pattern to
when it happens and when it doesn't.
I am using Xalan Java version 2.2.D11. I did not have this problem
with the version I was using previously (Xalan Java version 2.2.D8),
but I had to upgrade to the latest version due to bugs in D8 (it was
screwing up import precedence of attribute sets).
Can anyone tell me 1) what a DTM ID is (api docs are unhelpful) and
2) how I can avoid this problem?
Thanks,
Ryan

Okay, I found a detailed discussion of the problem here:
http://marc.theaimsgroup.com/?t=100455985000002&w=2&r=1
Looks like this is a limitation of Xalan-J, unfortunately.

I don't think this can be explained away as a JVM problem.
Even if Xalan or Cocoon is running out of resources, they
should be printing a more informative error message.
But since they were working fine with an older version of
Xalan, I suspect the resources are fine, and that this is a
bug.

In my case when I maked the .ear file for OC4J container I play moving
several files from/to lib directory and randomly the problem desapear,
but IMO it was because the JVM manages differents resources with several
combinations, also when the squid proccess manage less incoming
connections on the server the problem also disapear, then I think that
is problem of the JVM connected with the operating system resources.
Best regards, Marcelo.

I am running Cocoon as part of a build process, i.e. from the
command line (actually, called by Ant). It is not running within
a servlet engine or using hsqldb.
I strongly suspect that this is a Xalan bug, since D8 had no problems,
but D11 does. I guess I should post there. The strange thing is, it
only seems to happen when running from within Cocoon, not
when I run Xalan by hand.

I don't know the reason for this problem, but it seems that
it has something to do with the hsqldb.
In most cases deleting the cocoondb.backup file in the WEB-INF/db
directory and then starting your servlet engine again, solves
the problem.

I reported this problem some days ago. It is no a problem of xalan.
Is more conected with Sun JVM and the operating system resources.
Are you using Sun JVM 1.3.1 on Sun Solaris?
In my case this problem desapear removing the flag -server when start
the servlet container.
