Incremental Processing blocks

           Summary: Incremental Processing blocks
           Product: XalanJ2
           Version: CurrentCVS
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: org.apache.xalan.transformer
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


we are here experiencing problems with Cocoon 2 and latest Xalan 2.2
when we turn on the incremental processing of Xalan.

The environment is Windows 2K, JDK 1.3.1, Tomcat 3.3, Xerces 1.4.3. 
The problem occurs with the latest Cocoon 2 RC2 and the last
version of Xalan (D13).

When we put our server under some load, some threads seem to hang
forever and you never get a response. This is very easy reproducable
by using a frameset. If you hit 4 or 5 times the reload button,
one frame is blank and Cocoon seems to never return. For each
frame a Xalan Transformer Instance is used.
If you then hit reload again, Tomcat crashes! There is no exception or
anything else logged.

The problems seem similar to the threading problem we had
with the developer versions of Xalan 2.0 earlier
this year. 

However, turning off incremental processing and everything is running
fine again.

If you need more information, just let me know - I'll try my best.
