Sorry, I don't have any additional leads over what originally reported. I'd suggest to approach this by testcase analysis

Description: Once in a while group_replication.gr_start_stop_stress w1 [ fail ] Found warnings/errors in server log file! Test ended at 2018-01-30 14:34:11 line 2018-01-30T14:31:32.437285Z 19 [ERROR] [MY-011254] Plugin group_replication reported: 'Error while sending message for group replication recovery' ^ Found warnings in /mnt/workspace/mysql-5.7-param/BUILD_TYPE/release/Host/min-artful-x64/build/mysql-test/var/1/log/mysqld.3.err ok How to repeat: Perhaps ./mtr --big-test --suite=group_replication --big-test gr_start_stop_stress with a sufficient --repeat --parallel Suggested fix: Superficially it seems that the warning is expected given that the testcase starts and stops group replication for one node without syncing with completing recovery. gr_start_stop_recovery.test seems similar in this regard and it suppresses this and a few more warnings.
