Symptoms
SSH session closes after running any 'show cloning-group ...' Clish command (e.g, 'show cloning-group members') on cluster members with enabled Cloning Group.
Clish crashes with Segmentation fault after running any 'show cloning-group ...' Clish command.
After enabling generation of core dump files for processes with SUID permisssions per sk102130, core dump files for 'CLISH' process were generated in the /var/log/dump/usermode/ directory.
Core dump files from CLISH process contain the following stack:
[Expert@HostName:]# ./gdb /bin/clish clish_dump
...
Core was generated by `/bin/clish'.
Program terminated with signal 11, Segmentation fault.
