WCF-Custom Oracle LOB Adapter 3.0

Hi,

I am experiencing a rather interesting error every time I restart my BizTalk host which as a WCF-Custom Oracle receive location configured and enabled. When the host instnace is restarted the following error is logged to the event log:

After this error is received the host instance is stopped. The only way to get this configuration working is to disable the WCF-Custom Oracle receive location before restarting the host instance. Only after the host instance has started can the receive location be enabled. After this everything works as normal.

My question is why is this error occurring and how can I resolve it. It is quite annoying that I need to manually disable/enable only the Oracle WCF-receive locations when restarting the Host Instance.

Your comments and suggestions are welcome.
