StalePassiveConnectionService (ovsdb 1.14.4-SNAPSHOT API)

java.lang.Object
- org.opendaylight.ovsdb.lib.impl.StalePassiveConnectionService

All Implemented Interfaces:

AutoCloseable
```
public class StalePassiveConnectionService
extends Object
implements AutoCloseable
```
StalePassiveConnectionService provides functionalities to clean up stale passive connections from the same node before new connection request arrives, especially for connection flapping scenarios.
When new connection arrives all connections from the same node are pinged. The pings cause the stale netty connections to close due to IOException. Those have not been closed after a timeout will be closed programmatically. New connection request handling is then proceeded after all stale connections are cleaned up in the OvsdbConnectionService
