--- Comment #113 from Marcel <maes...@gmail.com> --- Just thinking loud... I don't think the theorie of gilles is right that there are other tasks runnung. Of course this may lead the other problems but not to the one we are looking for. When I look to the video of the scan I think the main difference is the precondition. I have a library with tousends of taged people. Some with a real tag others just in the db as unknown So in my case the new engine must do a huge merge process. Probably there is the error we are looking for. -- You are receiving this mail because: You are watching all bug changes.
