When you encounter a critical issue in FreeBSD, the sensible way to go about addressing it is to file a suitably complete PR, instead of just gritting your teeth, raising your blood pressure, and hoping that someone else will accidentally fix it in the next release. Of course, filing a PR is not a guarantee that it will be fixed (e.g. the "snapshot fills a filesystem" problems, which result from deeper architectural issues and in practise may require contracting a developer to get fixed), but at least you will have done your part. > > Without these two things there is really very little > > that a developer > > can do to try and guess what might possibly be > > happening on your > > system.
