UTL_HTTP.end_of_body Exception Error. Trying to Understand the Reason Why?

Question

I have the following PLSQL Function that returns a End_of_body Error. This started when we migrated from 10g to 11g. It is simple enough to capture so the error does not stop the Function Flow, but the error causes the OCI driver in OBIEE to error, which prevents the use of OBIEE IBOT to execute. Trying to understand why this error is occurring..not sure if we have a permissions issue on the UTL_HTTP Package or what?
Anyone seen this problem in 11g? Suggests on resolving would be great. Thanks.
