[unixODBC-support] occasional exceptions

[Chris Masiewicz]

I have an app that runs 24x7, querying a few databases every couple of minutes.  Occasionally, I get the exceptions listed below.

I'll add some code to generate a stack trace when these errors happen, but I was wondering if anyone had any ideas as to what would cause these exceptions on an intermittent basis?

Our DBs deny any database problems on their end.

I'm running 64 bit Ubuntu with unixODBC 2.2.11-16 and free tds 0.82.  The app is multi-threaded.

Thanks
Chris
