## Symptoms

- Output of '`top`' command shows that '`threshold_config`' process consumes CPU at 100% on Multi-Domain Security Management Server.
*Example* :

1. Connect to MDM/MDS over SSH.
2. Log in to Expert mode.
3. Run the '`threshold_config`' command.
4. Close the SSH session.
5. Open new SSH session to the MDM/MDS.
6. Run '`top`' command.

## Cause

'`threshold_config`' process runs in an endless loop after shell is closed.

When closing a Linux shell, it sends the SIGHUP signal to its child processes.

On Multi-Domain Security Management Server / Multi-Domain Log Server, in order to protect the MDS-level operations, the SIGHUP signal that closes processes upon shell exit is disabled by design.
