wireslessproxd flooding my system log

Question

Due to a disk problem i ended up in system.log today, only to find that about every 2-3 seconds the following information gets dumped into the log:

default 10:51:07.210542 +0200   wirelessproxd   Stop advertising for process sharingd (365) of type 16
default 10:51:07.210626 +0200   wirelessproxd   Nothing left to advertise, stopping
default 10:51:07.210861 +0200   wirelessproxd   Start advertising for process sharingd (365) of type 16 with advertising interval 432 (270.00 ms)
default 10:51:07.210933 +0200   wirelessproxd   advertisingRulesOSX - advertisements: (
    {
        kCBAdvAppleMfgTypeKey = 16;
        kCBAdvDataAppleMfgData = <07ff4c00 10020b00>;
        kCBAdvOptionUseFGInterval = 0;
    }
)
default 10:51:07.211104 +0200   wirelessproxd   Requesting to start

    {
        kCBAdditionalAppleMfgAdvertisements =         ();
        kCBAdvDataAppleMfgData = <07ff4c00 10020b00>;
        kCBAdvOptionUseFGInterval = 0;
        kCBMsgArgIsPrivilegedDaemon = 1;
    }
)
default 10:51:07.229012 +0200   wirelessproxd   Started to advertise for type 16 with error (null)

My system has been behaving a little bit strange lately. I never had similar problems before. I'm running High Sierra 10.13.5.

Does anyone know what is happening here?

wirelessproxd is the Wireless Proxy Daemon. It’s a service that handles certain networking functions.

"Advertising" means broadcasting a machine’s network identity so that other machines can find it. For instance, functions like AirDrop and handoff with your iPhone won’t work if your computer can’t be found. This function is essential for your wireless network to function correctly.
