Resolution

Validate the connection information is correct and the remote server is reachable, then raise the timeout if needed.

Set the reconnect tasks timeout (value is in milliseconds)

reconnect.tasks.timeout=60000

How to configure timeouts for remote EJBs invoking server under heavy load in JBoss EAP 7.0 / 6.4

Root Cause

The client failed to connect initially and registered a reconnect handler, the reconnect handler has a 10 sec default timeout. If the remote server is reachable and the connection information is valid, then the server could be under heavy load and fail to response in the given time or the network could be slow, in which the reconnect.tasks.timeout needs to be raised. Also the server could have issues such as garbage collection issues and might need tuning.
