glb_listener.c:79: Failed to connect to destination: 112 (Host is down) #27

Open MrMoronIV opened 5 years ago

MrMoronIV commented 5 years ago

My webserver sometimes returns 503 statuses, hence not working, a retry of the request always fixes it.

Howerver, at the core, this is what glb returns for me:

glb_listener.c:79: Failed to connect to destination: 112 (Host is down) And then a couple of time for 1 second and then no errors anymoer.

This happens every now and then, is this a known glb issue or do I need to investigate somewhere else?

In case someone is interested. I had glb + watchdog setup and everything seemed fine except for the host is down seconds. I've replaced glb with haproxy 1.9 with mysql-check and all problems seem to be gone.

I'm on an open stack platform. GLB seems to be too unstable for actual use on this platform (don;t know about others)
