Warning: 1 threads created by InnoDB had not exited at shutdown! InnoDB: error: return value 16 when calling pthread_mutex_destroy().

Server version: 5.5.65-MariaDB
key_buffer_size=2147483648
read_buffer_size=131072
max_used_connections=3
max_threads=153
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2432799 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
