Excessive pings to CalDAV server, like 2 per second

[xylyn]

Hello! I have an installation with the stock calendar and MMM-CalendarEXT3 modules.

I also run a local CalDAV server on a Synology.

Despite the fetchInterval and refreshInterval variables being set to 180000, MagicMirror is almost constantly chatting with the CalDAV server (keeping the HDDs from ever spinning down).

The DNS query log shows a lookup from MM to the CalDAV server about two times per second. The MM install is the chattiest thing on my entire network!

How can I go about troubleshooting this? I can’t imagine any reason why MM needs to perform a lookup more often than the fetch interval.

Thank you for your time!

@xylyn for test, if you disable the caldav module, does the network traffic go away?

@sdetweil Commenting out the calendar module in config.js doesn’t stop the network traffic until a reboot, after which it’s silenced.

Interestingly…the problem appears to grow with time. Looking back 24 hours ago, MM was around 300 requests per minute, and now it’s averaging about 400:

@xylyn the caldav module is getting g the data from the server
To create the iCal file the MagicMirror calendar module needs

I don’t know how the caldav module works at that level
