20.1 Legacy Series / 19.7 to v20.1/20.7 -> recurring high ping latency
« on: February 22, 2021, 09:45:19 am »
Hello,
since the upgrade from 19.7 to a higher version, we notified, that we have often a very high ping latency on our OpnSense Cluster. It happens only, of the packages goes through the OpnSense. We replaced the SFP+ modules, cleaned the fiber but .. since it happens on both physical hosts, we don't think, it's a network hardware issue.
What we have:
I've attached a Grafana picture as you can see, that we have much "noise". These causes, that our MariaDB starts to switch our Write Master.
We have also an nearly identical setup on the other side (both clusters are connected via a darkfiber). I say nearly, because the firewall rules are a bit different (because of the reverse side), but we don't now ... that we configured a thing, that causes the ping latency with a higher version than 19.7.
We red about problems, if the OpnSense is a VM ... and some Pyhton scripts steal the CPU ...but our hosts are physical. We have no idea, where we can find this issue.
Any suggestions ?

- Intel X520 (fiber)
