Hi, Thank you for your report but unfortunately, this does not give us much to go on. Can you upload the full report generated by ndb_error_reporter? Can you let us know if there's anything out of the ordinary, or new, that you recently did? kind regards

Hi, > I had a crash of the node1 There is no NODE1 crash recorded in the logs you provided. There are no recorded issues with the cluster at all in 2020. The only crash was the SQL node, and this I can't reproduce nor deduce what really happened from the log. The "(Got an error writing communication packets)" could be - network (or any other hardware) error - the high load so cluster was unresponsive (I cannot say this is a case as I don't see any high load at that time on the cluster) I don't see the management nodes for this event (you only have here 26-28 February, nothing for January) and in the data node logs, I don't see anything peculiar. It does look like you were running a backup and that you stopped some nodes (or whole cluster) that day but I don't see no crashes on the cluster side and can't say why SQL node crashed. kind regards Bogdan
