Hi,
Unfortunately that is down to blind luck. Take a look at the
EA UK forums when you get a sec to understand the scale of the issues.
The provider you mentioned is on average experiencing 4 crashes per server per day (this is from internal RSP mailing list), which is more or less what we're seeing. Some servers are crashing once a day and others 6+ with identical setups.
You might well find tomorrow your server is crash-free and another customer who has had zero crashes today has 5 tomorrow. That is the randomness of how EA's back-end and server builds are at the moment. It's a time game waiting for DICE and EA to sort it out.
If you consider there is actually very little to cause crashes in the configs; PB is either on or off, hostname, banner, description and rcon password. It's fairly simplistic. We are also seeing quite a lot of sales emails along the lines of 'we a rent server from provider xxxx and it's constantly crashing but yours seem fine'. Again, all we can say to these people is thanks, but it's pure luck either way at the moment.
