How can I reboot my VPS if it says "Cannot allocate memory"

  • 772

I'm having difficulty with memory usage on my VPS (CentOS) running PHP sites.

Until now I have been able to change things and reboot to try to analyze and fix things before the memory usage climbs again, but now when I type reboot it can't even do that.

How can I reboot my VPS machine and get out of this catch-22?

5 minutes later: now memory is almost totally maxed out, what could be causing this and how can I begin to fix it when the response time when logged in via SSH is so slow?

    Press the virtual power button (the VPS control panel provided by your hosting company should have this capability).

  2. Your VPS providers control panel may also have a feature which allows you to borrow additional ram for short periods of time to get out of tight spots like this.
