Unfortunately turning off RTM does not help.

Now I am in reboot hell - one reboot after another.

And SYS support? Ignoring all tickets.

So if I understand it - there may be a problem in SYS real-time monitoring which causes the reboots?

Try turning off RTM for a while to see if it is that?

Interesting Kamilleri ... there is some resemblance to your problem even though I run different distribution of Linux (specifically Ubuntu 12.04).

So if I understand it - there may be a problem in SYS real-time monitoring which causes the reboots?

Anyway, the lack of SYS support is very worrying. Their response time is 2-3 days and the response is not helpful at all.

What do you get on your syslog?

That's the weird part - there is no information that would indicate a problem. Just BANG - reboot out of the blue.

For example:

Thank you for the suggestion, Criot.

I am not using OVH kernel (yes - I learned the hard way some time ago). I was using "3.2.0-75-generic #110-Ubuntu SMP" kernel

Few minutes ago I tried to downgrade to "3.2.0-70-generic #105-Ubuntu SMP". I know this kernel works on a nearly identical SYS server - both in terms of hardware and software - with no problem. Unfortunately, very quickly I got 3 self-initiated reboots.

[Criot]

The most common cause is the OVH kernel, make sure you're using the operating systems distro kernel and not the OVH one.

Dealing with SYS support is like pulling teeth.

We were delivered a faulty server which keeps randomly freezing and rebooting.

The SYS support claims that they checked and "there is nothing wrong with the server" even though the server will reboot within minutes (or max. hours) after initiating a SSH session or sometimes even without connecting to the server.

Anybody had a similar problem? What shall one do in such a situation?

[Of course the server is paid up so they are happy to keep the money but obviously we cannot use the server]
