Tigase’s Watchdog was implemented to help Tigase close connections that have become stale or inactive. Sometimes the connection is delayed, maybe dropped packets, or a service interruption. After a time, if that connection is re-established, both server and client (or server and server) will continue on as if nothing happened. However, these gaps in connection can last longer, and some installations will rely on the operating system to detect and close stale connections. Some operating systems or environments can take up to 2 hours or more to determine whether a connection is bad and wait for a response from a foreign entity and may not be configured. This can not only slow down performance, but can lead to security issues as well. To solve this problem, we have introduced Watchdog to monitor connections independent of operating system and environments to keep those broken connections from becoming a problem.
