Description Jesse Glick 2010-10-18 17:39:16 UTC

Observed on deadlock.netbeans.org Hudson master; not sure what exactly initiated this, but seems to have been from profiler-main job. It seems that once in a while, the LogManager$Cleaner shutdown hook triggers profiler code which then blocks; see thread dump. This makes the simple.cpu.Measure process hang; SIGTERM cannot kill it, you need SIGKILL.
