Workaround : Set database parameter _skgxp_udp_timed_wait_seconds=0
_ skgxp_udp_timed_wait_seconds=0 disables the timeout of the LMS processes, so they continue reading messages.
LMS handles messages between the nodes e.g. cache fusion
Typically it waits for acknowledgment of received and sent packets
Disabling the timeout will mean it does not timeout on the acknowledgment , but keeps processing requests, waiting for acknowledgment to arrive.
Only set the parameter to 0 after guidance from Oracle support
