I am very concerned by to processes that look suspicious: brute and minerd. I would also check what those perl scripts are running.

It is normal the the command does not return anything. It would be a hardware or diver issue otherwise.

Check also if you have processes in uninterruptible sleep. Run as root user: grep "^State:.*D" /proc/*/status

Those are terminal commands. Connect with ssh or PuTTY on your server and run the commands. Edit your question and add the output.

comment ISC DHCP infinite lease time
You could create a script that is adding all new hosts to the static lease list. This script could send you an email when you run out of IP addresses in that pool. Or send you an email each time a new IP/MAC was detected in the network. In this way you have the convenience of DHCP, you have the same IP assigned to the same NIC. And you have full control to change all this in a instant if you need it, and you can have static IPs too if you must. Modern DHCP server can be instructed to send an ARP request before assigning a lease for an IP.

comment ps aux hanging on high cpu/IO with java processes
This is a very good argument. Thank you for rising up. However I think that the chances for strace to start when your swap is not answering are low, but not impossible. I will update my answer.

comment All my harddrives are around 10 MB/s read/write
You can use strace -c cp .... to determine where the CPU time is spend (reads/writes vs userspace). Then you can use sysdig, ftrace/trace-cmd or sytemtap to see what is happening at the kernel level.

So first determine what is the raw speed of the disk (both for linear and random operations), then compare it with the current speed.
