Pedro Ruivo commented on ISPN-6359:
-----------------------------------

I was able to reproduce it locally with trace logs. the problem occurs because the {{TxCompletionNotificationCommand}} is sent async and when the put happens, the key may be locked originating the contention :) Working in a fix...
