Right, few things we need to make clear here.
When a customer comes to us and goes "The server crashes" and we ask what they have changed. The natural assumption is what has changed.
"I updated Infistar and added some buildings to part of the map using the method I've used for other buildings."
Is what we get off the customer.
Infistar has caused crashes in the past, however this was more ARMA not being happy on one of the older ARMA updates.
Since our reply the customer has not gotten back to us, Infistar is the easiest part to roll back, if that didn't solve it then it would be the buildings added.
People saying stuff like
Is rather insulting, as we take all instances like this seriously. However either way this is down to something on the server itself, as this is the first report we have had of server crashes in literally months. As ARMA seem to of gotten their act together recently in terms of stabilising the game.
We have a step by step system on these kind of issues. The first being rolling back any changes, then running steam update to verify the game files, and then in extreme cases when its still happening is to move the server to another node to take the server itself out of the equation. If its still crashing then its 100% something added to the server.
