We have the error: Client timeout: timeout=0 iterations=2 failedNodes=0 failedConns=2
DEBUG: Node *** ...:3000: Error Code 11: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
The error occurs when reading from secondaries index in a long time (> 5-10 minituse). At this time, the CPU load increases about 15-20%.
Cluster has 13 namespaces, 12 indexes (2 text, 10 numeric).
Client: C#/.NET on Windows Server 2088 R2, 11 clients. Server: Centos 6, AS 3.5.4, 3 nodes.
We do not see any low errors on the client or on the server (like message, aerospike.log, other log and limits…).
What can you advise? What could be the reason?
