UDPClusterManagerOptions.useAliveCheck property

Whether announced servers are expired when they stop broadcasting.

Signature:

useAliveCheck: boolean;

Default Value

true

Remarks

When disabled, a server is removed only on an explicit down announcement — so a host that dies silently is never removed and keeps receiving round-robin sends.

The default can be overridden with the IMQ_UDP_CLUSTER_MANAGER_ALIVE_CHECK environment variable, which is read as a number when the module loads: use 1 to enable and 0 to disable. Any non-numeric value — including the word true — is read as disabled.
