It is not due to HA failover, we tried manual failover but didn't affect the GTMs. The iquery goes down, GSLB servers are marked red and then come back after some time.

 

I tried configuring the static ARP, didn't resolve the issue.

 

I configured MAC Masquerade, but, still the same issue. I am clearing the ARP once in a while until the TAC finds the resolution.

 

Can you suggest some procedure to delete the ARP via a cron job that runs hourly? can we spin up something like that and execute every 10 minutes or so.

 

Code we are running is 11.5.1 HF1, it seems to be buggy.
