Well, in case anybody ever looks at this bug, it may be a bug in the Ruby interpreter. This is fixed in Debian - https://bugs.debian.org /cgi-bin/bugreport.cgi?bug=876377
It would be great to get this fix backported to Ubuntu 16, as otherwise pcs is pretty much unusable. I've tried installing the PCS 0.9.164 .deb from Ubuntu 18 on Ubuntu 16, and can confirm that it still exhibits the same problem. ** Bug watch added: Debian Bug tracker #876377 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=876377 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772998 Title: pcsd runaway processes use 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcs/+bug/1772998/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
