I wonder if anyone can help me figure out what is going on.
I have a customer who is setup on a Vultr hosted freepbx 15 and has about 25 extensionsAfter a few days the odd extension will become unreachable for 60 seconds, then come back as reachable. As time goes by other extensions will start to do the same. If I leave it another day it will become more common. These phones are in five or six different locations and the fault can happen in any location to any extension. It’s almost as thought the PBX is running out of resources, yet CPU use is ticking over around 2% and i have given it 2GB ram and it shows .5GB spare.
HTOP shows no runaway processes.
