Hello,
I have a web application that processes files, which has been working
fine, however when it is put under a heavy load there is an occasional
failure. I have managed to recreate the error by sending 128 documents
at it in a serial fission, and I usually get 1 failure. Unfortunately
there is no log of the actual error, but I do get
"org.xml.sax.SAXParseException: XML document structures must start and
end within the same entity" on the client.
Can anyone suggest what the cause might be?
The environment is:
Tomcat 5.0.25
axis 1.1
xerces 1.4.4
The, access log has the following entry, the third line is the failure,
I think the first "500" is the internal server error, the second number
is always "500" which suggest the cause is the same despite it's
intermittent nature.

With logging set to debug mode I get the following error, I am hoping
this is familiar to someone.
