RecoverPoint and RecoverPoint for VMs: CLI session ends abnormally with "Killed" message when commands are run.

Many combined CLI changes in a large-scale environment can cause this issue. Running commands in large environments may cause CLI sessions to close abnormally.

If the window remains open, the user may notice a "Killed" message:

Cluster1> add_replication_volume group=CG copy=Copy1 replication_set=RSet1 name=device_DEV01
Cluster1> add_replication_volume group=CG copy=Copy1 replication_set=RSet2 name=device_DEV02
Cluster1> add_replication_volume group=CG copy=Copy1 replication_set=RSet3 name=device_DEV03
 
Killed

The following may appear in CLI logs (extracted.*/files/home/kos/cli/result.xx.log):

END OF LOGGER

Due to the size of the environment and many changes being combined within the same CLI session, the CLI process reaches its memory limit and crashes.

For example, when creating a Consistency Group, many changes are combined in the edit_group_settings command as a single change. Another example is "heavier" commands like get_group_statistics.

Workaround:
The following signed script can be run on the Cluster IP using putty/ssh > [2] Setup -> [8] Advanced options -> [4] Run script.
