MongoDB backups leave zombie processes #130

Closed i5okie closed 4 weeks ago

i5okie commented 1 month ago

After executing a backup, the script leaves a zombie PID. Resulting in a growing list of zombie processes. With the current script, the process ID is lost after execution, so proper termination is not guaranteed.
