Howdy,

Are you using a dedicated server, or a VPS? If it’s a VPS, are you by chance using OpenVZ? If so, can you paste in the contents of your /proc/user_beancounters file?

thansk for your reply.
we are using hyper-v to running ubuntu 14.04 linux

Howdy,

What is the output of these two commands on your server:

free -m dmesg | tail -30

here.
thanks

any can help?

Howdy,

I don’t see any obvious signs of resource problems, such as low RAM or oom-killer messages.

However, the services that run on Linux are reliable, they don’t tend to die on their own… so I suspect there’s something unusual going on there either with the VPS setup, or the hardware.

You may want to review your hyper-v setup, and the hyper-v logs, to see if there’s any kind of information about resource availability/usage, to make sure that it’s not restricting the RAM or other resources that are available.

Hi,

I just stumbled across this (admittedly a bit old) post.

If you are on Debian/Ubuntu or derived OS, this might be related to a logrotate/restart issue. See:
