Technical Tip: How to restart/kill processes on the FortiMail with CLI commands

Restarting processes on a FortiMail may be required if they are not working correctly.
Run the following command to see information on processes and their process IDs (PID): 

diagnose system top

The process ID is listed in the second column:

Additionally, it is possible to use 'grep' to find the list of PIDs for certain processes: diagnose system top | grep mailfilterd.

Alternatively, use the 'diagnose debug process list <process name>' command to list the specific process running on the FortiMail device.

For example:

diagnose debug process list mailfilterd

The PID is listed in the 1st column.

To terminate several selected processes, a signal can be sent one by one to the different PIDs: 

diagnose debug process signal 9 PID

Starting v7.6.3, the command has been modified as follows:

diagnose debug tools process list mailfilterd

diagnose debug tools process signal 9 <PID>

Summary:

Note: In addition to terminating several selected processes, a signal can be sent one by one to the different PIDs: 

diagnose debug process signal 11 <PID>
