Problem with SDS server disconnecting - Informix 1

Posted By: Jeff Filippi
Date: Sunday, 15 February 2009, at 12:54 p.m.

I am having a problem where my SDS server is disconnecting from the primary
after being connected for a while. I just upgraded a client to Informix
11.50FC3 from Informix 10.00FC5 in production today and I am receiving the
following issues with the SDS server.
I had to shut down the SDS instance until I can find out what is causing the
problem.
Has anyone seen this behavior?
Environment:
HP-UX 11.23
Informix 11.50FC3
KAIO - On
Here are the messages from the online.log file for both Primary and SDS
server.
