Pi was under high load this morning

[BlackHoleSun]

Hi,

when I got up this morning I found my network not responding. After a quick chekc I found that DNS querys where not resolved. I was able to SSH into the pi and found the following:

I was able to access the webui and this was also shown:

So no surprise this little thing did now work as expected

I've ran a trace and here is the token:
https://tricorder.pi-hole.net/LWVrmSYP/

Can you see anything in the log what happend there ? Never had that before.
Had to reboot the Pi to fix it quickly (had to work this morning).

Thanks for helping me.

Any help ?

Your screen capture shows a number of system level processes using significant CPU, which points to an OS-level issue.

Have you rebooted the Pi, and if so, does the problem resolve?

sudo reboot now

Thanks, I wasn't too sure if this is system or PI-Hole related. If it's systme I won't bother you guys. Thanks

Next time you see that many sh (shell) scripts running,
grab one of the PID's (Process ID) for one of them from the first column of the top output,
and post output for below one here pls replacing <PID> with the actual PID?

pstree -ps <PID>

Eg:

pi@ph5b:~ $ pstree -ps 437
systemd(1)───lighttpd(437)───php-cgi(473)─┬─php-cgi(504)
                                          ├─php-cgi(505)
                                          ├─php-cgi(506)
                                          └─php-cgi(507)

Maybe it shows where it spawned from and shed some light.
