FPolicy server frequently disconnects due to TCP port not Listening
Applies to
- ONTAP 9
- FPolicy
Issue
- After enabling a FPolicy policy, the external engine does not connect
- Fpolicy is running and listening on the configured port as per
netstat -an
Example of netstat -an
on the FPolicy server when service is not LISTENING on TCP port 2002, to which Vserver attempts to connect:
C:\> netstat -an | findstr 2002
Active Connections

TCP 0.0.0.0:445 0.0.0.0:0 LISTENING
TCP 0.0.0.0:49664 0.0.0.0:0 LISTENING
- When reviewing a packet trace, the TCP handshake fails
