Hi all,
I'm using httpclient v4.0.3 in a multi-threaded (currently 20 threads)
setup, and am receiving unexpected UnknownHostException s.
Some of the threads seem to be resolving without problems, I can
execute a manual dig at the same time without any issues and the
UnknownHostExceptions are coming in at a rate (1000s per second) that
indicates the Java part of the system isn't even connecting to named
(and possible attempts don't show up as udp packet on the lo
interface). I tried both with my own localhost named and with that of
my hosting provider, I also changed upstream DNS servers...
Sample stack trace below. What am I missing?
Thanks,
Chris
