Hi all,
I'm trying to get to the bottom of some interesting traffic that I'm seeing when troubleshooting some JBOSS application servers issues in my network. Going through traffic logs I can see a number of different session timing out for various reasons but one of the interesting ones are DNS lookups.
Essentially, I can see from the logs that DNS lookups are all being closed with a reason of 'idle timeout' with 1 packet sent and received and an elapsed time of 2 to 5 seconds however, whats confusing me is that DNS idle timeout values on Junipers is 60 seconds.
I think that this is fine and just the way that the Juniper logs a closed UDP session but I can't find any evidence for this anywhere I look.
Has anyone come across this before or know if my presumption that this isn't an issue is correct?
