We've recently upgraded to TeamCity 6.0.1 from 4.5.6, the upgrade was sucessful and we have been running without issues for several months.
It seems as of late(since the upgrade) the build history cleanup is no longer working. I've included a screen shot of our rules setup. Basically we keep everything but artifacts, and those have a 3 build limit. I know it isn't working because after a period of time the server fills up with artifacts and has to be manually cleaned.
I searched around and couldn't find any information on this issue, or even anybody else who had the same thing. I was wondering if anybody else had some insight they could offer.
