> Today one of my users did rename a folder containing ~25 folders. The RENAME did fail with a Cassandra level "Write timeout".
> This resulted in an half renamed folder, harming Thunderbird experience (subscriptions were not updated)
> We are investigating the cause of the write timeout. So far "reactor concurrency" do not loo like being to blame - but 16 concurrent renames is likely too much. I propose to decrease this parameter.
> Also, positioning a retry would help...
