Jigsaw crashing out

Big problem (maybe), has anyone else seen this?

I've been using Jigsaw for three months+ with no problems like this but the
server has suddenly decided to stop serving servlets after the first
request.

If I request a servlet, any servlets, even one which just opens an output
stream and returns some text, the server throws a NullPointerException
internally (ie. it doesn't get back to the browser as is usually the case)
and refuses to serve any more servlets from then until it is restarted.

It will still server static web pages OK.

I'm getting:

java.lang.NullPointerException:
	at java.io.DataOutputStream.flush(DataOutputStream.java)
	at org.w3c.jigsaw.http.Client.terminate(Client.java)
	at org.w3c.jigsaw.http.Client.startConnection(Client.java)
	at org.w3c.jigsaw.http.Client.SocketClient.run(SocketClient.java)
	at org.w3c.util.CachedThread.run(ThreadCache.java)

My SQL server (MySQL) is not involved, this happens with Servlets that
don't 'do' anything apart from return text, as well as much more complex
ones that have been fine for ages.

The output stream is being closed OK by the Servlet code etc.

The jigadm server is serving fine and the admin applet can be accessed ok.

The server error log contains nothing after the server startup message

This is Jigsaw 2.0.1 running under RedHat Linux 5.2 with JDK 1.1.7a.

Has anyone had this? It's not easy to see how to go about fixing it without
doing a full re-install.

Jeremy.
