I have a PHP script that uses exec() to kick off a separate PHP script in the background on my Linux server.
The script that runs in the background generates a potentially large PDF document (50+ MB) and may take a minute or two to complete. Once it finishes, it updates a database record.
I'm looking for a way to monitor the background script in case it crashes or hangs, and kill/restart it if necessary.
Any advice would be greatly appreciated.
