Hey
The ping limit in the configs has never actually worked on any chivalry server (amusingly the official servers with a ping limit don't actually have it working either
)
What we have is a custom made admin plugin that kicks for repeated high ping, however because of the way rcon works in chivalry, the plugin often crashes. Recently the plugin was disabled as there was a routing issue that caused everyone's pings to spike; it has been turned back on now, however for the reasons above it may be somewhat intermittent.
btw it's usually set to around 200-230ms because often after playing on hillside/citadel for a while, everyone's pings spike up this high and at 150 we'd end up kicking the entire server
