The software I'm using to monitor the defective server 1and1.com provides just notified me that the server has crashed again. By 1and1 hosting's standards this server is great, it stayed up for a whole week before it crashed this time. Once again, the logs and serial console show no reason for the crash. I rebooted it again
It's hard to imagine how 1and1.com stays in business with their normal server being this unreliable. Their management insists that they're not responsible if the server they provide crashes all the time. Nor will they repair or replace it. I get the impression that they don't have anyone on staff who knows enough about webservers and the linux operating system to troubleshoot problems like this.
