We have a 6 nodes causal cluster (1 + leader + 4 followers + 1 read replica) using v4.4.4 and since the last weeks we started to get this error a few hundred times per day, in waves:
Server error: [Neo.TransientError.Transaction.BookmarkTimeout] Database 'neo4j' not up to the requested version: 62656657. Latest database version is 62656083
We use bookmarks and read/write sessions depending of the type of queries that we need to do.
By using bookmarks, we understand that the query will be forwarded to a node that is up to date and, worse case scenario, it will end up in the leader that should always be up to date, right?
So it's not clear for us what could be the possible causes of this kind of error.
Could anyone give us an idea of possible causes or where to start looking for issues?
Just in case, this is our
Happy to share any more details if needed.
Thanks in advance.
