Bob, >From reading XALANJ-2439, the error you are getting is based on an internal hard limit of 65536 DTM IDs.
Why 65536 and not another number is probably an indexing optimization of some kind, I am not sure. I think the 16 bits of a DTM ID is stashed in some larger structure. Therefore, increasing RAM will not help. The JIRA seems to say that there are DTM ID leaks, so that's another avenue of investigation. If you are so inclined you could try to study the code to see how to increase this internal limit. The patches in the JIRA are old and may no longer apply to trunk (which is in an unknown state) or the 2.7.x branch ( https://svn.apache.org/repos/asf/xalan/java/branches/xalan-j_2_7_1_maint) I recently pushed out 2.7.2 but there are not many folks that are active on this list ATM.
