Description

Server_Session_Timeout closes NRPC sessions that have shown no activity for the specified number of minutes. This frees up licenses, memory, and sockets – important on servers with many clients that keep their Notes sessions open for hours without using them.
Clients reconnect transparently on the next call; users do not notice anything beyond a minimal delay.

Example configuration

Server_Session_Timeout=240

Notes & pitfalls

  • Value in minutes (not seconds, not hours).
  • 0 = never time out – can lead to “session leaks” on large servers.
  • Affects only NRPC – HTTP / IMAP / POP3 have their own timeouts.
  • Too short (< 60) → constant reconnects, higher auth load.
  • Recommendation for mail servers: 240 (4 h); application / hub servers: higher.
  • Monitoring: show stat server.sessions.*.
