I am running Influx 1.7.6 on Ubuntu 16.04. I am using tsi1 and have tried various wal-fsync-delay in my config file from 0ms to 5000ms. I am running the ubuntu as a virtual server on my physical ubuntu server and writing to the database on a RAID 6 array with spinning disks.
Mostly, I am writing data from Node-RED to influx using the influxdb node and I seemingly randomly get generic internal server errors (as shown in Node-RED debug panel) after writing data. However I have checked, and data is definitely written to influx.
Does anyone have any idea why these errors appear or if I need to modify settings either on nodered or influx? Here is a screenshot to show the debug node output of the JSON to write to influx followed by the error message the influx node spits out and then my terminal inspection of influx to show the value is actually there:
