Sublime Text 3 has started hanging hanging for me sometime within the last 6 months. This is certainly happening on CentOS 7, and may have been happening in one of the Red Hat Enterprise Linux 6.7/6.8 builds.
Every time I try to open a file, create a new file, or save a file (maybe only save as), the editor stops responding to key and mouse events, although it repaints fine. Looking at the WCHAN field in ps, I see that we’re waiting on futex. A this point, only a kill will exit the program; it never becomes responsive again in that session, even after accidentally leaving it hanging for several days.
This happens whether or not I’ve imported my license, and with a brand-new installation in a local filesystem as well as over NFS. It happens even if I’ve started a clean environment with /usr/bin/env -i csh -f before running.
Sadly, I do have another CentOS 7 machine on a different network where Sublime is still working, so there is something I’m missing about the environment I’m running in. Here are some details from where it’s running:
% cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
% uname -a
Linux myhost.mydomain 3.10.0-327.36.3.el7.x86_64 #1 SMP Mon Oct 24 16:09:20 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
This is preventing me from using Sublime at all on this network. I’m having to make do with Atom. Any clues or suggestions for further troubleshooting are welcomed.
