Yeah. As I mentioned in my original post, setting the hostinterval  
does alleviate, to some extent, the issues I'm seeing- but only if I  
set it up to 15 SECONDS or higher (not milliseconds), thus resulting  
in an essentially unusable probe. Ping shows RTA's of around 600 ms  
typically. I have the timeout set to 2 seconds, which is well more  
than the latency I typically see, but even so that would only affect  
the last packet or two, and I never get more than two or three packets  
back total, regardless of how many I send out. And ping shows no loss-  
just FPing which shows 100% loss after the first few packets (few  
defined by how high I set the hostinterval for). Thanks for the  
response though :)
