            Bug ID: 278076
           Summary: GnuTLS 3.8.x breaks any recent version on Samba,
                    'GnuTLS could not generate a random buffer'
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)

14.0-RELEASE-p6. x86_64.

I updated to GnuTLS 3.8.4 and Samba slowed down to a crawl. The daemon created
a strangely named log file (.log) containing the following error, which I'd
seen during my previous attempts with GnuTLS 3.8.3. It never happens with
GnuTLS 3.7.x and lower.
