Client heartbeat is timed out

[Abdülhakim Ünlü]

Hi,

After the load-test I mentioned in the below post:

https://groups.google.com/d/msg/hazelcast/rVcK3M4uO_Q/bUnTs-YJCQAJ

In hazelcast server logs, following logs are printed continuously, although the clients on that endpoint is shutdown:

WARNING: Client heartbeat is timed out , closing connection to Connection [0.0.0.0/0.0.0.0:5701 -> null], endpoint=Address[137.58.63.49]:40992, alive=false, type=JAVA_CLIENT

Which hz version are you using?

Can you make a github ticket, because it smell like a bug.

Any updates on this issue. I keep seeing this in our logs as well?

Thanks

Hello Abdülhakim,

Can you also share the logs prior to these logs. I am especially interested in the logs about socket closing:

Something similar to: Connection [" + connAddress + "] lost. Reason: 

Better yet, can you share all the logs for both client and the server. At least the logs when the heartbeat failure started?

Regards,

ihsan
