Hi everyone, I host a server with few services running for my family and friends. The server freezes sometimes. Where the services stop responding. If I try to ssh into the server, it takes a lot of time (3 to 5 mins) for it to connect. After being connected, every letter I type takes 2 to 3 mins to appear on screen.

Seems like the server is overloaded with tasks. But I am not sure what load it is running. I have netdata installed. I could pull up following screenshots for insights.

Can someone please help me in troubleshooting the issue?

I have tried testing stress testing my RAM and CPU, and they were fine. But I would start troubleshooting from scratch if you have recommendations for testings softwares.

Please also let me know if there is anything I can pull from netdata to help in trouble shooting.

System Specification:

System RAM

Disk I/O

Total CPU Utilization

Idle Jitter

    Okay. Thanks for the insight. Planning to do this:

    You need to monitor which process is using all the memory. The easiest way is probably to keep htop running in a screen or tmux session, periodically connect, and look at which processes have the highest used memory.

    Will report back with findings when it crashes again. Thanks for all the help.

      It’ll probably be obvious before it crashes, you can see in the graphs that the “used” memory is increasing steadily after a reboot. Take a look now and see which process is causing that.
