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
