I see that you have changed this from 5 to 3. There is a reason why?
That depends. First of all, it’s just a guess - starting from scratch avoids having to do a detailed scan to find a problem, and take more time than you intended. To solve the problem.
Often users do several tests using the same volume and sometimes mix previous configurations and even run posting and wall files on top of each other. Overwriting files. That can work, but generate problems.
A while ago I saw this happen with other users. We don’t know what was done to achieve this. But starting from scratch usually helps.
It would be great to understand the steps to replicate this and then see if it is a problem in Dgraph or in the use of DB. But, the last time I saw someone report this was over 9+ months ago. And was a heavy user.
Either way, you will have to stop your production to solve the problem. It is not possible to understand exactly what is happening only through logs, yaml, or testimony.
