Editing SimTX API/Limits and errors (section)

== Session limits ==
Each server enforces its own limits. The defaults are:

{| class="wikitable"
! Limit !! Whole server !! Per client
|-
| Sessions (receivers and transmitters) || 128 || 16
|-
| Receivers || 64 || 8 per IP address
|-
| Transmitters || 16 || 4 per account
|-
| Connections of any kind || 256 || 32 per IP address
|}

Operators can change these values.

* '''Receiver limits''' are counted per client IP address. A start over a limit is refused with <code>LIMIT_REACHED</code>.
* '''Transmitter limits''' are counted per account. When the ''server'' is full, transmitters wait in a queue instead (see [[SimTX API/Packets/TxQueue|TxQueue]]), unless the account holds <code>session.queue_skip</code>.
* '''Account capabilities''' (<code>game.max_stations.N</code>, transmitters on air at once; <code>game.max_receivers.N</code>; <code>game.max_sessions.N</code>; <code>tx.pa_limit.N</code>) are checked in addition to the server limits. See [[SimTX API/Permissions]].
* '''Station limits''' (<code>maxSessions</code>, <code>maxTransmitters</code>, <code>maxReceivers</code>, set by the owner and clamped by <code>game.station_sessions.N</code>) apply to station-bound sessions. The owner is not counted against the station's receiver limit. See [[SimTX API/Stations#Limits|Stations]].
