mysqld would be forced to restart when pmm-admin add mysql. The version is 5.7.13-6-log Percona Server. The following info is from mysql error log.

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 http://bugs.percona.com/

key_buffer_size=33554432
read_buffer_size=131072
max_used_connections=879
max_threads=100001
thread_count=17
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 38516969 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

    It does not look as PMM bug.

    Looks like there is an issue with Percona Server, may be its configuration, may be out of memory.
