Kill Hanging Flow Service

We have a custom flow service to ftp EDI files to VAN. We use B2B scheduler to schedule that flow service to run every 15 minutes. When the next session starts, it will check if the flow service is still in use, if so, it will skip.

I would like to find out… for some reason, if the flow service is hang, are there anyway to “kill” the flow service? So far, we can only restart B2B as a work around for the hang service issue. However, it really affects our production.

Any idea, input and comments would be appreciated.

Thanks in advance.
