Why would an OpenVZ VPS crash by doing a speed test when using Shadowsocks?

    HostBrr aff best VPS; VirmAche aff worst VPS.

  • Crash means the end.

    Therefore, OP means the end is nigh.

    VM shuts down, and rebooting it is not possible from the provider's control panel for a while (from couple of hours to days).

  • And the problem is not just about shadowsocks, It happens with wireguard as well.> @lindy54 said:

  • How much memory does your OpenVZ container have?

    But Openvpn worked without such issues, so low ram is a problem with shadowsocks and wireguard for just one client?

  • The simplest solution for the answer would be do the same task but with half a gig of RAM.
    If it doesn't scream the end, you know the culprit.

    Shadowsocks and Wireguard-go need more RAM compared to the OpenVPN daemon. Simple as that. The more recent versions of each upped their RAM requirements. 256MB is not sufficient to run a system + the two clients, unless you really slim down the underlying system processes, use some swap space, and only run either Shadowsocks or Wireguard-go, but not both at the same time.

    Likely the reason it's crashing is due to OOM killer killing a needed system process which causes the container to halt. When you don't have a SWAP to fail back onto, the kernel has to resort to OOM killer to not run out of RAM, lest the entire thing comes crashing down (which is likely what's happening here).

    The fact that the VPS is unable to start again for

    (from couple of hours to days)

    suggests that there may be an abuse script on the providers side that is causing this.
    Care to name the provider?

    v2ray and wireguard-go work fine in webhorizon NAT-256 vps.

    Yes, I also suspect that the problem may be caused by an abuse script. The funny thing is that the main ipv4 address gets inaccessible for that period too (from different IPs, so it's not an IP blocking mechanism). I think there will be some issues if I name the provider.

    But I have the same issue with v2ray unfortunately.

  • So, I removed wireguard completely and shadowsocks works well for speeds above 100 mbps without "crashing".
    I doubt that it's a ram issue though, because shadowsocks continues to run ok under much higher ram loads.

    wireguard-go, of course.

    Have you opened a ticket with the provider regarding this?

    Open a ticket with the provider. They might help find the reason as they have access to things you dont.
