Multiple SBCs disconnecting every 1h at the same time

[GThom]

Hey all,

I started noticing this issue about a few days ago and it had been constanly doing it. All of my remote sites SBCs just keep disconnecting at the same time every 1h then reconnect on their own immediatly. CPU seems to spike at that exact moment as well. Any hints on what to look for or does anyone had simillar issues ? I am thinking this is so timed that it has to be related to a routine task.

I am planning to restart the instance this weekend to this if this behavior will stop.

Thanks !

Just to clarify, all SBC's are on the same remote location?
Also have you ensured that the PBX server and the SBC's are under the 3CX Recommended Hardware specification:

Thanks for the reply, all SBCs are at different remote sites handling the local phones. 3CX runs on google cloud. We used Raspberry Pi 4 which are in spec according to your link and have been running this way for almost 1 year. Now suddently we started seing these coordinate reconnections happening.

I have fail to identify a common cause but will start with the services restart.

I would suggest first to check the BLF keys limitations as per provided guideline first.
Since you have defined that this happens at a specific time and it is the same for all the SBC's, most possible you will need to create a support ticket so we can check further.
