Hello Mark, It has been some time since I have looked at the probe routine in the 3.8 version of UHD, but it sounds like the discovery packets are having routing problems. Do you have an N210, N200, or USRP2 anywhere on the network?
We can probably give some assistance to discovering the root cause of those messages, but it sounds like your real issue is that the retunes are taking longer than you expect. How long are they taking? How are you measuring the retune time? What daughtercard are you using? We usually find that if you are running Centos and an older version of UHD means that updating is not possible or prohibitively difficult. It does bear saying that the X310 and daughtercard code bases have advanced over the past two years. The UHD 3.9 branch provides a nice middle ground where you can get access to many of these updates without large architectural changes.
