I have a VPS CentOS Server hosted by GoDaddy. The database for my website is going down once everyday. I have two websites hosted on that server, a Wordpress and a Magento website. The connection to database breaks everyday and both websites stop working. Both websites have daily auto-backups enabled. But the backups are not being created everyday and I believe that these auto-backups are preventing the server to keep in running state. Is there a way I can get to know why the server or database services are going down. I contacted GoDaddy but the guys said this is a Managed VPS plan and you are responsible if there is something wrong with the codes, and claimed that there is no issue with the server or database. They asked me to check the error logs (error_log, login_log and access_log). I am not sure if I have found anything. I have found these entries in error_log and login_log.

Is it possible that the resources are not sufficient and causing the outage?
