Editing SimTX API v24/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, and the public server may use different ones.

* '''Receiver limits''' are counted per client IP address. A receiver over a limit is closed without a message.
* '''Transmitter limits''' are counted per account. A request over the account's limit receives a [[SimTX API v24/Packets/TxReject|TxReject]] naming the limit. When the ''server'' is full, transmitters wait in a queue instead (see [[SimTX API v24/Packets/TxQueue|TxQueue]]).
* '''Account capabilities''' (<code>game.max_stations.N</code>, <code>game.max_receivers.N</code>, <code>game.max_sessions.N</code>) are checked in addition to the server limits. Both must allow a session. An account without a <code>game.max_stations</code> capability may run 3 transmitters. See [[SimTX API v24/Permissions]].
