i have 3 vitalpbx servers with arround 80 tenants each, and 1k extensions each. 2 servers are Vital3 and one Vital4
Only on vital4 server when a call go to a queue with 3 or 4 static extensions the cpu go very high when ring on extensions. Its not about big traffic becouse i test it at 04:00 am when no one doing calls… and if put only one extension on queue occours too less severe cpu use. This effect is not observed on vital3 servers.
In my case this happens when ring an extension that isn’t available.
I change the users extensions queue from static to dynamic, That maintains the cpu normal.
But definitely this doesn’t happen with v3 only 4.
Its exact opose situation: when static extension is online cpu go high, extensions offline dont add the effect. Looks like rebooting pbx reduce effect…all tests done when no one using pbx
