MYSQL crashing with signal 11

Previously I added same crashing with different error log. This time it shows different error. Could someone please help with what can be the failure here? I'm using NDB cluster and master master replication in same database.

And also I'm doing a load test which handles 2000TPS as peek time transaction. Having 2 mysql servers, 2 NDBD(Data Servers) and 1 server for cluster manager.

13:11:15 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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=2501
max_threads=2500
thread_count=2008
connection_count=2002
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1124431 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x7f6560048a70
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...
