Description

For each defined Notes port (e.g. TCPIP, ClusterPort), Domino maintains its own pool of worker threads that handle incoming connections. For ports without an explicitly set pool size, Server_Pool_Tasks_Default applies. On heavily used servers (many HTTP sessions, many NRPC replications), a default size that is too small becomes the bottleneck – connections are accepted more slowly or rejected.

Example configuration

Server_Pool_Tasks_Default=40

Notes & pitfalls

  • Only applies to ports without a specific <Port>_Pool_Tasks setting.
  • Takes effect after a server restart.
  • Observable via show stat Server.Trans.PerMinute and show stat Server.NetSession*.
  • Complementary to Server_Pool_Tasks (general worker pool) – do not confuse the two.
