FreePBX 16 Memory issue

All of our FreePBX’s we spun up at the same time (FreePBX 16.0.40.3) are displaying a strange behavior where the used and cashed memory will slowly consume the free memory, which is normal. What is not normal is that instead of reusing the cashed memory, FreePBX will start to utilize swap, which eventually causes problems until the memory is manually cleared. We are mitigating with a cron job to clear memory periodically until we can determine a better next step.

Anyone else observing this issue? Any insights?

FreePBX does not manage memory, the OperatingSystem does, did you add any process to your base install? (because that’s almost certainly where your problem is)
