Phil Sorber commented on TS-2017:
---------------------------------

{noformat}
14:18 < amc> PSUdaemon - TS-2017. Explain, please.
14:21 <@PSUdaemon> this was debugged my mark
14:21 <@PSUdaemon> so he has more details
14:21 <@PSUdaemon> but when a UDP packet came back for a request ATS made, but 
came from the wrong IP
14:21 <@PSUdaemon> it would timeout for 20s
14:21 < amc> Poke him until he comments on the bug.
14:21 <@PSUdaemon> and our wonderful DNS is behind a load balancer and one of 
the nodes does not have the VIP set properly
14:21 <@PSUdaemon> so occasionally we'd get a response from a different IP than 
the one we asked

> DNS lookups stop for a period after ATS receives a response it was not 
> expecting
