From one day to another 50% of the processor graphs are not drawed. I get the famous “Error Drawing Graph” message, but only on processors. And I monitor powerdns, the graph for one of the powerdns queries is not even made (
I checked validate.php to see what could be wrong, but I always get the same, even though I see in the logs that all devices (17) are polled within 20 seconds)

This seems to be happening since a newer update. Anything I can check before I pull my hair out? 
MariaDB [librenms]> select * from pollers;

(I wanted to place some screenshots here, but it doesn’t let me, so I’ll followup)
These were all working fine the last time I logged in (two weeks ago). Restarted snmpd on the servers a couple of times, updated the OS, no change. There are also no pollers in the “Unpolled devices” list.
Thanks very much
