I experienced this same issue running MySQL 8.0.21 on CentOS 7.9 in a 3-node Group Replication cluster this past week. As best as I can tell, a user performed a large and unbounded UPDATE statement, likely causing a spike in memory usage, and a number of on-disk temporary tables. The Linux kernel OOM killed the mysqld process, and upon attempting to restart, crash recovery failed. The mysqld service entered a crash loop. I did attempt to use innodb_force_recovery=1 with no success (same behavior). This was the output of the startup, and I'll see if I can augment this report with a more reproducible scenario -- however this is the first time I've seen this behavior, and am not sure I can reproduce. nnoDB: Progress in percents: 123:15:38 UTC - mysqld got signal 11 ; Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware. Thread pointer: 0x7fc4a8e16cc0 Attempting backtrace. You can use the following information to find out where mysqld died.

I should also point out that in this 3-node cluster -- much like the original reporter of the ticket, two of my hosts ended up in the same state, while the third server just reported that it was still holding a SECONDARY role in a cluster where one node had been evicted and the primary node was in UNKNOWN status.

hi, @black 无 can you give me the download link for version 8.0.17 you are using? linux generic or redhat rpm?

hi @Andrew Ernst, you are using the community version or commercial version? If community version, which OS version are you using? linux generic or redhat 7 version? It's better give me the exact download link for me to analyze. Thanks!
