The problem is that no matter what i do and no matter how many times i reinstall the server there is one specific problem which drives me crazy...
After 16 hours up time all the sites hosted on kloxo suddenly vanish... and by vanish i mean that they are not opening in browser.... no matter if there is some application installed on the domain or not the website is not opening.
Only Kloxo Panel is working and i can login.
I have to manually execute sh /scripts/restart-all in order to resolve the issue.
There are no error messages recorded in the logs which is like a ghost living in my server...
Despite the above mentioned problem Kloxo and all related services are working like a charm.
But I can`t restart the server every time the websites are gone and can`t open from browser....
2 weeks already every couple of days i reinstall the server with some hope that this time the problem will disapear..., but nooooo.
