<P><FONT COLOR="#000080" SIZE=2 FACE="Trebuchet MS">I'm trying to diagnose a problem that just came up on our spread-based messaging layer. For months we have had applications running fine in production and yesterday I noticed some problems. It seems I can only see messaging traffic when the client and server are both running on the same box. This was never a problem before and I can't think of anything that changed (no new software, no new config file, etc.). I've written my own application-level "sniff" tool, but its not helpful since its not seeing any cross-machine traffic. I was wondering if there are any spread-level sniffing/debugging tools that could help me understand what might be wrong.</FONT></P>
