Hello,

sorry when this is a FAQ. What is the exact meaning of:

connection_input: conn=4412677 deferring operation: too many executing

It means there are too many operations active on the given connection, so further operations on that connection will be queued until some of the active operations complete.

and what could be done against it ?

Fix the client that is sending so many operations at once without waiting for them to finish.

Thanks

Sepp
