Hi,
I use Percona-Server-5.7.12-5-Linux.x86_64.ssl101
In mysql.err file ，It throws the following error
。。。。。。
09:05:03 UTC - mysqld got signal 11 ;
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.
Please help us make Percona Server better by reporting any
bugs at [url]System Dashboard - Percona JIRA
key_buffer_size=33554432
read_buffer_size=1048576
max_used_connections=40
max_threads=501
thread_count=9
connection_count=7
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1063797 K bytes of memory
Hope that’s ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong…
