Get below error when start slave process
22:01:17 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.
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.
Please help us make Percona Server better by reporting any
bugs at [url]System Dashboard - Percona JIRA
key_buffer_size=33554432
read_buffer_size=524288
max_used_connections=1
max_threads=2002
thread_count=3
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3137339 K bytes of memory
Hope that’s ok; if not, decrease some variables in the equation.
