Greetings, Y'all!

We just had an interesting situation, which is not a good thing in this business.

All applications that connect through s certain port number (as determined by $INFORMIXSERVER) were hanging.  When I connected through a different server alias - which maps to a different port number - all was fine.  I even tried that with plain dbaccess.  If I specified a database on the server alias for that one port it would hang; but specifying the database @ another alias/port, it connected.  And whatever I set INFORMIXSERVER to, the onmode -ky also hung.

The only cure was to bounce the engine.  In middle of CyberWeek?  YIKES!!    I had to kill an oninit process to drop the engine.

Problem solved for now.  But does anyone know of a forensic (or even real-time) method or utility that can tell me what had happened to the port?  Overloaded? No error message anywhere, not in the online.log, not in /var/adm/messages.

I have the OS (Solaris) and network experts in on this but we are all drawing a blank.  IMHO Informix in the victim here, of a network issue.  But I have users clamoring for answers so we can either prevent it or catch on quicker when it happens.

Thanks much for ideas here.
