Internal server Error

           Summary: Internal server Error
           Product: Cocoon 2
           Version: 2.1.2
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: core
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: kumar_1000@yahoo.com
                CC: kumar_1000@yahoo.com


We are getting "internal server error" from cocoon 212 under high load, or 
moderate load over 30-60 minutes of run. The issue is very consistent. We run 
Cocoon 2.1.2 on JBoss 3.2.3 and JRE 142_05.

On every occurrence of this error, the message below is first logged in 
sitemap log.

Soon after the message below is repeated on all other cocoon logs, until the 
severs are restarted.

We have also noticed that the error occurs (reported in cocoon logs) randomly 
with other components also, like
