We just experienced a disasterous situation involving an ftp thread. Cloverleaf was not able to connect to the recieiving fax server due to a VPN issue, and the thread went into an error state. As a result, two our inbound threads stopped ACK’ing back, and the systems kept sending the same message out to our clients for hours. We just brought up ver 5.6 rev2 on our Win2003 server. I am using the same tps_create_ack_hl7 proc for the inbound threads that I had on the previous ver, and never saw this behavior. Anybody experience a similar issue, or have a suggestion to prevent this.
