In all honesty, I believe the best would be to push 3.3.6 (or better yet, 3.3.7 due on Oct 31) into the next LTS point release due to the large amount of fixes both small and large that went into that release. I'm not entirely sure whether that's possible, and if so, how, but with my upstream hat on, I strongly recommend 3.3.6+ for production use, instead of trying to port back patches on top of 3.3.4 (in the end, you'll end up with 3.3.6 anyway, save a few minor things).
Packages for 3.3.6 are already available - built for 12.04 as well as for other Ubuntu and Debian releases - from http://asylum.madhouse- project.org/projects/debian/ ** Changed in: syslog-ng (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049202 Title: syslog-ng-mod-mongodb has deadlock problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/syslog-ng/+bug/1049202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
