The session token renewal does 1) Read the old token 2) Write a new token 3) Delete the old token If two processes succeed to read the old token there can be two new tokens because the queries were not run in a transaction. This is particularly problematic on clustered DBs where 1) would go to a read node and 2) and 3) go to a write node. Signed-off-by: Christoph Wurst <christoph@winzerhof-wurst.at>
