Diagnosing server load

Hi all.

 

This problem wasn't happening but then it started randomly and its happening more and more. So right now, my server is near un-usable. Its currently sitting at a load of 60. (please see screenshot)

The server isn't doing anything, the load will at some stage come down and the server will be usable again but I am trying to work out what exactly is causing this. If i open netdata during this time, it shows IOwait as the biggest issue but I am not sure what is causing that. 

 

This is the result of "free -hm", am I running out of ram and its swapping to drives?


root@ASTRO:~# free -hm
              total        used        free      shared  buff/cache   available
Mem:           3.6G        2.9G        190M        473M        558M         14M
Swap:            0B          0B          0B

 

Like right now I have 10% of kswap0 and 10% of unraidd, is that it swapping to the disk?

 

I don't have a cache drive and the server is essentially ideal right now. Any ideas on stuff to look at?

You're getting out of memory errors, probably one of the dockers, best bet would be to shut them all down, turn on one by one and leave it a few days to try and find the culprit.

 

Why am I not getting email notifications of your replies? This comment is not directed at you, just speaking out loud.

 

Thanks for the tip, I am pretty sure its the NZBGet docker as its the only container doing anything each day. I also install iotop to help me, thanks for your help I appreciate it.
