Bert, I can’t seem to get this latest version to run right. I build my RPM. I launch it with the following:

What I can do is make packages that will be binary identical to the real 3.3 once you 'bless' them as having solved your issue. This would save you an upgrade. Would this work for you? Bert.

Do you know how far off this is at all? Our production systems are still displaying the tcp listener issue but I have a watchdog script restarting it before it maxs out the number of clients so no customer impact, I would be loathed to look at upgrading until we have the full 3.3 deb package if possible.

And does it no longer happen when running Brad's test > script? Simon, Sadly we found that the previous code drop, while stable, still exhibited the same problem. We've fixed yet another bug that might be causing the issue, and we are currently testing that. This drop can be found on http://svn.powerdns.com/snapshots/pdns-recursor-3.3-pre.tar.bz2 If you compile the program below, and run it on your pdns server, you'll probably see it print '0' and then a very large number. If you could share that output with us, it could tell us if we are on the right track. http://pastie.org/1124088 http://pastie.org/1124088.txt To compile, save as .cpp file and compile with 'g++ -O2 testing.cpp -o testing', and run with './testing'.
