HTTP 400 BadRequest: WSO2ESB 2.0 loops and produces some GB of logfile

Hi,

My problem is quite the same as posted in http://wso2.org/forum/thread/8492.

My colleague tried to check a firewall rule via telnet.
He posted an irregular HTTP Request to the WSO2ESB, see the telnet output:

HTTP/1.0 400 Bad Request
Date: Tue, 19 Jan 2010 14:46:24 GMT
Content-Length: 50
Content-Type: text/plain; charset=US-ASCII
Connection: Close

The result on the WSO2ESB is that the following log statement occurs every milisecond, so 2-3 GB of logfile is written:
2010-01-19 15:46:24,311 WARN  [http-Listener I/O dispatcher-1] [org.apache.synapse.transport.nhttp.HttpCoreNIOListener] System may be unstable: IOReactor encountered a runtime exception : null

Could you provide a fix for this? We need to restart our ESB in this case, that's what we would like to avoid.

Thanks in advance,
Alex
