Oracle Adapter Intigration Freeze Up

Has any one else had a similar experience and if so what did it seem to be related to?

Issue: Remote 4.1.1 Oracle Adapter using 8.1.7 libraries talking to a Oracle database server 8.0.5. Integration polls database table every 6 minutes. Adapter queue showed one document that never was processed. Client status connected, Adapter Configuration Tool Green Ball. The Oracle connection is from the Midwest to Porto Rico.
There were no errors in the broker.alert or files.

Thanks in advance.

Did you run the adapter in debug mode? If so what were the results? Also try running the adapter in command line mode. I’ve seen a few instances where an adapter worked fine in debug mode, but would not run in normal mode.
