I recently started using ActiveBackup on a Synology NAS and since enabling the ActiveBackup for M365 have had problems with my PFSense going offline and requiring me to turn off/on the power to the device.
My internet connection is a 1GB cable connection (1gbps down / 45 mbps up). My PFSense box is a Zotac Brix MI660Nano (quad core intel, 8gb ram, Samsung SSD).
When running the ABforM365 sometimes it will die after a few minutes and other times it can download 50-150GB before an issue occurs. I can see during this time it may have download speeds of anywhere from 5-70MBs as reported by the PFSense dashboard. PFSense will then randomly go totally offline - non-pingable totally locked up, can’t access the internet from any device. If I force it off and back on the downloads can resume and internet access from other machines resume.
I can see an error 65 in the PFSense gateway log as well as a php-fpm error (after the fact) but I can’t do or try anything as its totally locked up and unresponsive.
I have run this same PFSense box for years with no issues when downloading large files (several GB files, streaming video) or even uploading TBs of data to a backup provider.
I am kind of at a loss as to what the issue is or how to track it down. Any ideas on how to resolve this or track down what’s is happening?
