Well I guess it is some kind of log I can see and I have look inside the
but still can't find what have happend to my ubuntu server.
Three days in a row it just stop working and just freeze and I have to power off and then power on again. When it frezze it just stop working and I can't use SSH or the keyboard so I just have to power off. It is maybe some script I have done something wrong but when I don't know what to look after then is not easy for me to fix it :)
The one that got written last so do a
ls -ltr /var/log/*
The one at the bottom is most likely the one. Otherwise it will be one with a date that is relatively new.
would always be my 1st to check.
One thing you can check is all the crontabs you have. A problem will arise if you have a script that is executed every X minutes and takes X+Y minutes to finish where the script does not check it is already running... you will, at some point, clog the server with that script.
