>          Issue Type: Bug
>    Affects Versions: 1.16.0

> A failure was observed in 
> DistributedMulticastRegionWithUDPSecurityDUnitTest > 
> testMulticastAfterReconnect due to suspect strings with fatal-level logging 
> of "Membership service failure: Member isn't responding to heartbeat 
> requests".
> Investigating the logs showed all members reporting long statistics sampling 
> wakeup delays, indicating resource issues:
