FreePBX stops switching entirely every Monday morning

Have a Sangoma FPBX16 running at AWS. I have a number of these and this is the only one that gives me trouble. I have been fighting and troubleshooting this problem off and on for almost a year and know my way around Linux. Every Monday morning the system stops switching/routing calls. fwconsole restart resolves the problem. Any ideas? Thanks so much guys.

No, not really. You haven’t really described what happens, shown the state of anything before a reboot or any debugs that might indicate what the issue is. Provide those and we can come up with ideas.
