业务链接异常，请问这个是数据库bug？
2018-05-28T00:46:30.213044Z 34 [Warning] IP address 'XXXX' could not be resolved: Name or service not known

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=22
max_threads=151
thread_count=22
connection_count=22
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68275 Kbytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x0

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