一共三个数据库,原版本均为5.6,升级到5.7.13后开启多源复制,做成两主一从,发现频道名称同名。
在从库执行重置所有从机后,从库自动重启。

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=1
max_threads=151
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68189 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x7f9550000b10

where mysqld died. If you see no messages after this, something went
terribly wrong...
