Description

Parent smbd occasionally exits on signal 6. Have not completed root cause analysis of this yet. Separate bug ticket. This results in shares being inaccessible. Customer asked for script to restart samba if it enters this state. Existing logic in AD monitoring does not catch this situation.

Arguably this is should be monitored separately (i.e. part of smb monitoring, not AD monitoring), but AD exists and monitoring is being rewritten in the future. The simple fix to this is to add additional check for samba_server status. This has added advantage of perhaps getting us out having to do a full restart of Active Directory when it's not warranted.
