Hi, We are having a 5 node Cassandra cluster running in version 3.0.13. Recently we upgrade the Cassandra cpp driver on the application side from cassandra-cpp-driver-2.6.0-1.el7.centos.x86_64 to cassandra-cpp-driver-2.15.3-1.el7.x86_64. After the upgrade, Cassandra system.log is continuously filled with the below message.
INFO [SharedPool-Worker-11] 2021-04-26 07:11:18,445 Message.java:615 - Unexpected exception during request; channel = [id: 0x08a9bc0f, L:/ 10.50.11.123:9042 ! R:/10.50.11.182:44734] io.netty.channel.unix.Errors$NativeIoException: syscall:read(...)() failed: Connection reset by peer at io.netty.channel.unix.FileDescriptor.readAddress(...)(Unknown Source) ~[netty-all-4.0.44.Final.jar:4.0.44.Final] Even though these INFO level log prints are causing system.log to be rotated 4 or 5 times a day, there is no functional impact seen. What could be the problem here? Let me know if more details are needed. Regards, Renoy Paulose
