One node is crashing repeatedly.

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...

Trying to get some variables.
Some pointers may be invalid and cause the dump to abort.
Query (7effb4e03890): is an invalid pointer
Connection ID (thread ID): 202009
Status: NOT_KILLED

I am unable to understand why it is crashing and what should I look at.

I have already tried following but server still crashes with same output.
1) Removed Percona Server.
2) Removed all data under /var/lib/mysql
3) Rebooted server
4) Install Percona Server
5) Sync with cluster (full SST)

It still crashes with same error.
It does not crash immediately but randomly after about 18-22 hours.

Server : Percona-XtraDB-Cluster-server-56-5.6.19-25.6.824.el6.x86_64
