The TSQL subsystem failed to load

Hi,

I get the error 'The TSQL subsystem failed to load' when running a scheduled SQL Task, the actual step that fails seems to vary. Once this error occurs the job becomes suspended and I have to restart SQL Agent in order to be able to attempt to re-run the job. The job then re-runs fine with no errors.

I have looked on various web sites including Microsofts and can't find any reference to this problem.

I am using SQL Server ODBC driver version 3.81

Any help would be greatly appriciated.

Thanks,

Darren Ison.
