hrev50001 running in VMware Fusion 7.1.3.

Haiku was running for some time mostly idling. When I switched to it from another Workspace (in OS X) it was sitting in KDL. Might be related to #9721.

Still here in hrev51425.

Leaving Telegram running in the background seems to trigger it.

comment:3 by pulkomandy, 3 years ago

Got this to happen 2 or 3 times this week, at a slightly different address (deadbf33 instead of deadbefb).

Could be because of running the webkit testsuite, or maybe just DHCP traffic going on.

udp_endpoints does not show anything.
