Monitor instance bigip *.*.*.*:443 UP --> DOWN from gtmd (no reply from big3d: timed out)

Yeah. It;s a known bug with v11 when you have multiple traffic-groups. Since multiple ALSO includes using both the default floating and default non-floating traffic groups for some addresses, it hits more often than you'd think.

 

 

The iqdump output is pretty clear when this is happeneing, if you have a working unit and a non-working unit to check. When the unit isn't working, you're missing VIP and MONITOR messages in the stream. Hence gtmd times the VS out because it's not seeing the messages for the VS coming from the LTM. The message actually makes sense. It's just a little terse (Because it's not the comms timing out, it's the missing messages in the stream that cause it).

 

 

I was told it'll be fixed in 11.3... But I did manage to convince support to get me an engineering hotfix for 11.2.0HF2. I just hope it'll get rolled into 11.2.0HF3 (Because the fix isn't in 11.2.1).

 

 

FWIW the fix appears to be somewhere other than the big3d binary itself... The version of big3d didn't change. And replacing the EHF big3d with EM's big3d binary still works correctly too.
