The lxc lock had nothing to do with the segfaulting - and no, the new hanges will simply swap out use of named semaphore for a flock on an open fd (so that they get auto-cleaned if process is killed). Any potential for segvs *should* be found while I test. > I'm just interested, wheter it's safe to upgrade to the latest > version in the next few days. Unfortunately there is only daily ppa > for 0.9 tree. raring and saucy are based on 0.9. For the most part the daily ppa is actually very stable. It goes through quite a bit of automated testing before it gets published. It's what I use on my main dev box, though when I"m working on something that takes a few days, I sometimes end up a few days behind while I test my feature. I think this is the second time a bug has been exposed mainly through lxc-list (because it uses quite a bit of the api), so lxc-list should be added explicitly to the testsuite. -serge ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
