For total update: The replica agreement thread that send the entries flowed the consumer that is not able to process fast enough the entries. So the TCP connection get full and the RA sender sleep on the connection to be able to write the next entries. Sleeping on the poll or write the RA.sender holds the connection lock. It prevents the replica agreement result thread to read the results from the network. So the consumer is also halted because is can no longer send the results. For incrementatl update: During incremental update, all updates are sent by the RA.sender. If many updates need to be send, the supplier may overflow the consumer that is very late. This flow of updates can fill the TCP connection so that the RA.sender hang when writing the next update. On the hang, it holds the connection lock preventing the RA.reader to receive the acks. And so the consumer can also hang trying to send the acks. Fix Description: For total update there are two parts of the fix: To prevent the RA.sender to sleep too long on the poll, the fix (conn_is_available) splits the RA.timeout into 1s period. If unable to write for 1s, it releases the connection for a short period of time 100ms. To prevent the RA.sender to sleep on the write, the fix (check_flow_control_tot_init) checks how late is the consumer and if it is too late, it pauses (releasing the connection during that time). This second part of the fix is configurable and it may need to be tune according to the observed failures. For incremental update: The fix is to implement a flow control on the RA.sender. After each sent update, if the window (update.sent - update.acked) cross the limit The RA.sender pause during a configured delay. When the RA.sender pause it does not hold the connection lock Tuning can be done with nsds5ReplicaFlowControlWindow (how late is the consumer in terms of number of entries/updates acknowledged) and nsds5ReplicaFlowControlPause (how long the RA.sender will pause if the consumer is too late) Logging: For total update, the first time the flow control pauses, it logs a message (FATAL level). If flow control happened, then at the end of the total update, it also logs the number of flow control pauses (FATAL level). For incremental update, if flow control happened it logs the number of pause (REPL level). https://fedorahosted.org/389/ticket/47942 Reviewed by: Mark Reynolds, Rich Megginson, Andrey Ivanov, Noriko Hosoi (many many thanks to all of you !)

A tombstone entry does not have its entry mutex allocated, and it will be dereferenced. Fix Description: If the entry is converted to a tombstone, there is no need to refresh it in the first place. Skip the cache refresh if its a tombstone. If its not a tombstone, we also need to return the cache entry if it was not changed in betxn postop, because we incremented its refcnt while checking if it was updated. https://fedorahosted.org/389/ticket/47750 Reviewed by: nhosoi(Thanks!)
