but how did we escape noticing this bug so far? I understand that DNS caching can hide this bug. Brian, do you have lots of hosts to resolve?
There have been ~1200 unique hosts check in within the last log retention period, but I think it's more like ~1000 daily. In the past we'd bumped the dns cache size up to account for that, but that hasn't changed in a long time.
Or did you change the DNS caching parameters?
Nothing changed there recently (years). The only thing I did was try to backport the 3.3 series of syslog-ng specifically for the threaded option to try and work around some scaling issues we were seeing. The reentrant problem mentioned earlier strikes me as familiar from other past projects, though I couldn't say for sure off the top of my head. I'm happy to test it if you've got some packages for me somewhere.
