Killing the rrdtool process didn't do anything as a second after another rrdtool process spawned. i had to kill all /usr/local/bin/create_rrd_graphs.plx --mode monthly,daily and then was able to pkill rrdtool. Few minutes later it was back draining my cpu so i had no choice but rename /usr/local/bin/create_rrd_graphs.plx to /usr/local/bin/create_rrd_graphs.plx.old. Today i let it run for three hours but it didnt finish whatever it was doing. I then cleand up the /var/log/reporting/rrd folder (as per https://community.sophos.com/utm-firewall/astaroorg/f/utm-9-2-beta/65432/9-190-bug-high-cpu-load-after-up2date) but it didnt make any difference.
I didn't do any updates on the firewall so i have no idea what could cause this. my CPU is "Intel(R) Xeon(R) CPU E3-1230 v5 @ 3.40GHz" so i don't think it is struggling with RRD graphs.
