Oracle : Ошибка ORA-28576

"lost RPC connection to external procedure agent"
*Cause: A fatal error occurred in either an RPC network connection,
the extproc agent, or the invoked 3GL after communication had
been established successfully.
*Action: First check the 3GL code you are invoking; the most likely
cause of this error is abnormal termination of the
invoked "C" routine. If this is not the case, check for
network problems. Correct the problem if you find it. If all
components appear to be normal but the problem persists, the
problem could be an internal logic error in the RPC transfer
code. Contact your customer support representative.
