Hi @zoltan.zvara ,
Sorry for delayed reply.
I checked uploaded logs (both uploads) and I have noticed few things
- there are few forestdb related crash and indexer restarts but these are recoverable errors and indexer does recover after the restart, we will try to investigate the reason for it but that is not a cause of problems.
- There are lot of node status “unhealthy” messages. This looks to be the cause of problem. These messages are not for any particular node but for different node at different time. . We are looking at if these errors can be due to some issue in one of the components but in the logs we also see related connection/call time out errors, connection closed errors. Hence we suspect these could be related to cluster networking setup. I would request you to check if the cluster has stable network.
