In addition, while the build is waiting on the executor to acquire the lock, it is reported as running on the master.
E.g. the axis2-1.6 #225 build right now shows: "Started 42 min agoBuild is being executed for 42 min on master" Andreas On Sat, Jan 7, 2012 at 14:33, Andreas Veithen <andreas.veit...@gmail.com> wrote: > BTW, here is a screenshot that shows the problem: > > http://people.apache.org/~veithen/axis2-builds.png > > The three Axis2 builds all use the same lock. > > Andreas > > On Sat, Jan 7, 2012 at 13:38, Andreas Veithen <andreas.veit...@gmail.com> > wrote: >> We've seen similar issues with Axis2 builds in the past.
