Instead, munged consumes an entire cpu and must be forcibly terminated with a SIGKILL." Patch below is the upstream patch to fix this issue, and a least if works for me. Regards, Loic >How-To-Repeat: # /usr/local/bin/sudo -u daemon /usr/local/sbin/munged -F --key-file=/usr/local/etc/munge/munge.key Process is then uninterruptible and cannot be killed with SIGKILL. >Fix: Applying upstream patch.
