I have been searching the forum for references to this error that is showing up on our log for an outbound thread,”PDL exception: code 1, msg device error (remote side probably shut down)”. This is followed by a no response with timeout error, and then a resend. The thread Outbound Prop. Inbound reply is set to 90. Most of the topics where it is listed indicate that it is mostly viewed as some kind of warning rather than an actual comm. error. We have spent several days troubleshooting a situation where our Win2003 server is sending TCP_SYN resets to a UNIX host, and it looks like these resets more or less correspond to these errors. Does anyone know specifically what these errors mean, and has anyone figured out how to deal with them? The firewall on the UNIX side was terminating the connection when it saw these resets, and they have fixed that. The interface is working more or less, but I would rather fix this than live with it.
