According to the Sybase documentation, "for environments requiring dbinit(),
the application must not make any other DB-Library calls after calling
dbexit()."

Your program violates this restriction. You should only call dbinit() once
at the beginning, and call dbexit() once at the end.

Hi,

I am connecting through the FreeTDS 0.60 to a SQL Server 2000 machine. I
don't do anything but just dbinit() and dbexit() in a continuous operation
and it fails after sometime (~ 5-10mins). I am attaching the sample code -
please let me know what could possibly go wrong.

Thanks,

Sameer
