I've a debian squeeze server with nginx, php5-fpm and mysql. All this services from some point started to shutdown at random time. And they not seem to crash or something, syslog:
Feb 14 14:02:14 xxx mysqld: 130214 14:02:14 [Note] /usr/sbin/mysqld: Normal shutdown
There is also an isp control panel, and around this shoutdowns there is some cron from isp manager running. What can cause that or where should I look to find out more information?
