Ubuntu 14.04.3 LTS (GNU/Linux 4.4.0-83-generic x86_64)
Description
Replication suddenly stopped, and the slave server "Slave_IO_Running" value was "Connecting".
I've tried to connect to the Master. And I couldn't.
It didn't stop by "service mysql stop".
I've killed mysqld process.
Now it's running.

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.

|
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.

read_buffer_size=1073741824
|
max_used_connections=256
|
max_threads=402
|

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 843080049 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...
