Description

Different dtests in several CircleCI builds failed with teardown failure due to network failure with the error:

test teardown failure
Unexpected error found in node logs (see stdout for full details). Errors: [WARN  [epollEventLoopGroup-5-4] 2021-09-14 09:35:15,897 ExceptionHandlers.java:134 - Unknown exception in client networking
io.netty.channel.unix.Errors$NativeIoException: readAddress(..) failed: Connection reset by peer, WARN  [epollEventLoopGroup-5-4] 2021-09-14 09:35:15,897 ExceptionHandlers.java:134 - Unknown exception in client networking
io.netty.channel.unix.Errors$NativeIoException: readAddress(..) failed: Connection reset by peer]

For example, test_view_metadata_cleanup from materialized_views_test.TestMaterializedViews failed in this build or test_expiration_overflow_policy_reject from ttl_test.TestTTL failed in this build
