Hi Guys, I want to help to find out what is causing this problem. It's been about four days, a website wordpress migrated to another server, it falls every 12hrs or 4 hrs or until after 24hrs drop disconnects and I have to reset the password to be running the site.

Ja looked xml attacks and load robots ... but it does not find anything like that.
They cited problem of having little memory on the server, but the site was running with less than 256MB of memory on the previous server and never fall.

And I could not solucioanr the problem.

What might be causing this to wordpress falling the server?

Follow all the logs that pussuo to help identify.

Your mysql error log doesn't go back to the origin of the issue but I am still leaning towards this being an out of memory issue. Unless you take steps to optimize MySQL, the default configuration on a 512MB droplet will almost always use the available memory and crash. I would recommend first adding a swap file and keeping an eye on things. If the crashes halt you should still go back and see if you can optimize your MySQL configuration further as it will run slower when using swap space on your disk.

Thanks for the help , I'll do it.

Do you think that would attack problems, trojans and malware and DDoS ? Something similar?
