----------------------------------
Summary: ListenTCP processor does not release connections if
client disconnects abruptly
Key: NIFI-6031
URL: https://issues.apache.org/jira/browse/NIFI-6031
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.5.0
Reporter: Endre Kovacs
Assignee: Endre Kovacs
If a client connected to ListenTCP processor, gets disconnected abruptly:
(eg.: they disconnected their VPN to NiFi's network), the client-TCP-socket on
the NiFi node will be seen lingering for an extended amount of time (eg.: such
socket can linger in established state even after 12 hours after disconnection)
Or till a manual workaround is done: the ListenTCP processor is restarted.
An ideal fix would be to allow the underlying OS to poll the socket if the
remote side is still alive, and disconnect it if not.
