If you have observed this error on a consistent basis then most likely its due to firewall issues otherwise if it happens intermittently then it could be due to heavy load on that server/network. Engage network team, find out the server load/statistics, check GC logs, traffic volume, lb logs etc.
If you are using distributed/replicated caching then it could be related to clustered network or server overload within that cluster.Find out recent changes in the setup since you observed the error.

It's likely a network issue, the system cannot open a socket to listen for UDP packages.
Thanks a lot the issue is solved now.It was a port that was blocked.
