Hi everybody,

I don’t understand what’s happen since I upgrade percona xtrabackup to 2.1.3.  
My node is crashed and I have this error in my log :

07:53:55 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](http://bugs.percona.com/%5B/url%5D)

key\_buffer\_size=52428800  
read\_buffer\_size=131072  
max\_used\_connections=13  
max\_threads=2002  
thread\_count=6  
connection\_count=6  
It is possible that mysqld could use up to  
key\_buffer\_size + (read\_buffer\_size + sort\_buffer\_size)\*max\_threads = 4432877 K bytes of memory  
Hope that’s ok; if not, decrease some variables in the equation.
