Asterisk is the process consuming all the RAM / triggering the OOM. We have 4 GB of RAM(hosted on AWS). We use to run an old version of FreePBX(can’t recall which version) and it worked very reliably(we had uptimes longer than 1 year). The only reason for the upgrade was to get security patches… Any pointers on identifying if this is a memory leak or if something in the code base changed and it now requires significantly more RAM would be much appreciated!
The screenshot below is after 5 hrs of uptime(cronjob rebooted server at 3am), and likely no phone calls have been made yet as it’s before business hours.
