900 MHz 450i, SMs couldn't connect after crash

We had a 900 450i AP crash yesterday, and when it came back up all the SMs were unable to connect to it.  They instead all connected to another AP which was using a tertiary colour code, so they were dropping session and reconnecting to the wrong AP over and over again.

Once I restarted the AP, SMs started connecting to it again.

This is worrying to me because I don't know what the problem was, so it could happen again.

Here is the crash dump from the log file.  Does anybody know what this stuff means?  It would be nice if I had the resources to troubleshoot these kinds of things myself without having to bug the support staff.
