Status / Monitoring graphs stop randomly.
It seems that in the last few days the graphs under "Status > Monitoring" seem to randomly stop working. (Screenshot attached.)
This goes for every graph it has, including bandwidth, packets, etc, they all just go to 0.
The only thing I can correlate it with is an increase in the firewall's troughput, and an upgrade of its RAM amount in the last few days.
A restart of pfSense fixes the issue, however it is not possible to keep doing that.
Any ideas or suggestions?
