I am new here in this forum. I just set up openvz about a few months already. It was working fine. I created several VPS inside Host node. Each VPS have their own public IP which is accessible from internet and they worked very well.

Recently, I encountered a problem. I could not connect nor ping to some VPSes. I do not know what is the cause because before it was working fine. If I restart that VPS container, I could ping and access it again. But after a few hours, It is not accessible again. The problem could be fixed if I restart it.

I have searched in google and in this forum but still could not figure out yet.

I have my own solution but I do not like it. I wrote a bash script for checking if the VPS is not accessible from or to. If the error occurs, let it restart. And I notice that such error occurs every 4 hours.
