Hi Techies ,


We are able to see Cassandra write query in our environment in case of high load , Please have a look over below log snippet .


Error String :

WARNING 8511 com.l7tech.external.assertions.cassandra.server.ServerCassandraQueryAssertion: 10903: "Perform Cassandra Query" assertion failed due to: Cassandra timeout during write query at consistency TWO (2 replica were required but only 1 acknowledged the write)


As per error ,looks like it Its not getting ack in time from both the replica  hence timing out with above error  But in our environment there are 4 Cassandra node and all are running fine with out any issue .


Software version that we are using :


Gateway :9.2 Gateway  2 node standalone (A and B)

Cassandra : 5.1  Total 4 nodes  Cassandra  (A,B ,C and D)

OS : REHL 6.7
