Issue in Getting Cluster status MGM API (libndbclient.so.4) (no replies)

I am using MySQL Cluster (7.1.15a-1.rhel5) and my application is getting state of the Cluster by using the MySQL Cluster Management API . While Calling the ndb_mgm_get_status() method on Management Handle, application is having segmentation Fault after running about 3-4 hours continuously. Here is the back trace of the core File generated :-
