Thanks for the insight, unfortunately I am passing parameters into my
external procedure and returning a numreric value which is passed onto the
rest of my plsql routines.
Here is my c function:
-- ************* START OF FUNCTION CHECK_FAQ ************************
-- This procedure references an IN variable for the external C function
-- RetrieveURL and maps the library in the database which points to
-- the C external procedure to be run. This external function will
-- return an integer value for the request time (positive number) or
-- an error code (negative number).
-- *************
FUNCTION check_faq
(RetrieveURL IN VARCHAR2,
timeout IN BINARY_INTEGER)
RETURN BINARY_INTEGER
AS
LANGUAGE C
NAME "rnt_url"
LIBRARY MY_C_LIB
PARAMETERS (
RetrieveURL string,
timeout int);
I have to restart my callout listener to have my program successfully run.

Reed,
Don't know how it works in your case but remember that external
procedures are dynamically loaded. If you are using static variables,
they may be reset anytime. The reason may be that your proc is flushed
out of memory, then called back.
