The hotspot main thread does nothing except wait for all other threads to exit. Which can trigger this bug. This happens for example on a 2.6.32-220.23.1.el6.x86_64 kernel. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
