CPU Exhausted

[voiped]

Happy Friday to all. I'm using a Virtual App Server in HyperV Version 10.2.02 One X is enabled and we use it off site occasionally along with Web Collaboration. Intermittently I have been getting 100 percent usage and a CPU exhausted message. When I first noticed it seemed to be 100 percent all the time. I added 2 cores some RAM and NUMA and it looks like this. I don't really notice any performance issues but I'm wondering if I did anything wrong when I set this up. We have about 15 users so the system has pretty light traffic.

How many users on the IPO using one-x?


BAZINGA!

we had one that was put on the open Internet and a smart hacker went into the system and used it for other purposes than IP Office.
They either downloaded stuff or mined bitcoins.
Not sure which one it was because I was only hearing about it.
Yes all passwords had been changed but the customer wanted easy ones and they put it on the Internet unknowingly. Great It department

I have maybe 6 power users. It's not used a lot I also monitor periodically when onex users are logged in Never seen more than 2 logged in. At 100 percent usage I'll see no one logged in.

I also periodically would see people trying to login from outside. Since I changed the default port numbers I haven't seen any outside mischief. I think I'll try shutting down onex service and see if usage goes down. I'll also close the ports to the outside but I really don't think the systems been hacked. I seem to remember that I continued to see hi usage even after I reinstalled the server.

Login to Linux and run "top" to see which process is using the CPU.

Then I think the server is not powerful enough.

Just a wild guess, but I had a customer who had something like this happen while we only had a few demo users programmed on their Primary server in a Server Edition solution. It was virtual in a VMWare environment. It turned out they got hacked. The One X services would be at 100% CPU, and after a service restart or a server reboot, the CPU's would be ok for a couple of hours before climbing back up again. Luckily this was long before we started programming anything so it was an easy fix to just decommission the server and re-deploy it.
