btsntsvc64.exe process high cpu utilization when idle- oracle client

Hi,

I have a c# function that uses oracle client 10g 64 bit in order to call a stored procedure on Oracle server.

I call this function inside my orchestration. My orchestration is bound to a 64 bit host in BizTalk.

Everything is working fine (functionality wise). but there is a performance issue. After some time the cpu utilization goes above 50% all the time for this host. and the memory is increasing by time.

I always close the connection after i make the SP call.

Any body have encountered this before?

All help is appreciated.

Thanks.
