I started getting the "too many open files" error after upgrading to 2.14.0 (but had 2.14.0rc5 before). My "ulimit -n" is 1048576, so it should be more than enough. I removed the whole ~/.cache/pants and .pants.d and all that - no help. It's also kind of bad that I can't even run "./pants --version" which should not try to start pantsd. What can I do? I will try to restart, but it shouldn't be needed (I'm thinking about what to do if this happens in CI)
