Hi,
We have a queue Manager which is running on a virtual machine with the following :

MQ 5.3 CSD 10
Win 2003 virtual server

We started to see the following error about 2 weeks ago and I am not sure what could cause such a thing :



Event Type: Error
Event Source: WebSphere MQ
Event Category: None
Event ID: 9208
Date: 2/28/2007
Time: 9:38:02 AM
User: N/A
Computer: OMIPVSB
Description:
Error on receive from host omipvsb (127.0.0.1).

An error occurred receiving data from omipvsb (127.0.0.1) over TCP/IP. This may be due to a communications failure.

The return code from the TCP/IP (recv) call was 10054 (X'2746'). Record these values and tell the systems administrator.


Any advice to where I should start looking ? Is this somthing which need to be looked at by the Sys admin of the machine ?

It sounds like something is trying to create a client connection from the local machine - or there's a bug somewhere that's causing the ip address to be reported wrong...

I guess you should figure out if there are client apps that *should* be running against the loopback address. If not, you should figure out what applications *are* trying to do this.

Otherwise, look at the error logs for the client.

Start by looking to find out what 10054 is. This is a Windows sockets error code. My first guess is that a firewall intervened to break your connection - I don't see what else might break a connection on 127.0.0.1
