Crash in table_cache code

2018-04-24 8:13:19 6264 [Warning] Aborted connection 110550 to db: 'dilas' user: 'op' host: '172.20.13.19' (Got timeout reading communication packets)

180424 8:39:29 [ERROR] mysqld got exception 0xc0000005 ;

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.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help

diagnose the problem, but since we have already crashed,

something is definitely wrong and this may fail.

Server version: 10.2.14-MariaDB-log

key_buffer_size=2147483648

read_buffer_size=10485760

max_used_connections=236

max_threads=65537

thread_count=213

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2126896 K bytes of memory

Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x278c5ce3298

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...
