OVH Finland already dealt with it.

This is just for information so everyone reading this thread can make their own conclusions. OVH staff of course can see this information straightaway. I can also say that the "high" bandwidth consumption or "high" memory consumption are NOT correlated with the freeze ups. Usually CPU time on TOP is quite low, but the load indicator is showing something like 6+.
I'm not talking about 'production use', but I still would expect 'normal' and some what stable (in certain parameters) operation. I surely acknowledge it's budged server and I'm not expecting phenomenal (lol) CPU, IO, network performance. But the fact that the system completely freezes over for 2-3 minutes is something I really can't stand. And that's not only 1-2 times, it's repeated. Like I said, I once complained about it. After that it worked just as I would expect and I was very happy with it. Then those freezes came back. Now it's working again like a charm.
If you think about the freeze ups, that's not something you can tolerate even with personal website. Web sites should be reachable, even if slow, that's ok. But if it doesn't work at all. That's bad.
I completely agree with Marks comments from OVH. That's exactly what I'm asking for. I'm IT pro and we provide services to customers using several cloud hosting solution providers. UpCloud, OVH, Sigmatic, Hetzner and a few Telcos. I know you get what you pay for. Only think I'm dissatisfied with are the freeze ups. Which clearly seem to originate somewhere from the host platform. Based on my experience the vm host (If you can even say so when using OpenVZ / LXC) is running out of memory and swapping heavily, that's just what it feels like. Even ssh shell echo can at times just simply stop for 2 minutes.
Everything is now ok, and I hope the situation remains like this.
