My FreeBSD box keeps shutting down after 20 minutes or less of ontime. Xorg starts just fine but I keep finding .xsession-errors and these weird files that I cant figure out the meaning of like .xsmU97EBA and .prxlzzacC. Are the two issues related? What can I do to get rid of these log files?, and keep my machine running. If the two aren't related then what could be the problem?
