I have a problem that I can't figured out how I can fix it.

We have a procedure that sends data to an oracle database. Sometimes, we receive a C000005 Fatal error. When issuing a SQLEXEC command.
I don't think that the problem is in the SQLEXEC because sometimes, the same command executes succesfully. It seems that this error did happened to other peoples. Is there a way to prevent this error.

We are using VFP6 SP5.
