Hi @simplilearn,

Your HW specs seem great. A couple of questions:

1. Have you ensured that Windows Updates installed?
2. Are you using any 3rd party softwares installed, such as Antivirus software etc?
3. Have you checked the 3CX Management Console Activity Log to see if something was leading up to the high CPU usage?
4. What does the Windows Event Viewer say? Was there a crash or was the service stopped for some other reason?

Hi Vasilis,

The CPU usage is normal now after purging the contacts from the PBX has settled the CPU usage to about 35%.

Hi @simplilearn,

How many contacts did you have added to the system when the CPU was running high?

Hi,

We found the issue is with the contacts which were synced with salesforce CRM and now no more is in use in 3CX.
We purged the contacts after taking backup, now it is reduced to 10% if calls are reaching 100 even.
