Message-ID: <20000629135236.G5671@intrepid.net> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 1.0.1i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG When I last upgraded -stable from source (18 June), my box stopped local delivering mail reliably. Upon investigation, it looks like procmail is acquiring a lock and then hanging. By turning on verbose messages in procmail, sometimes the mail goes though, and sometimes a lock is acquired and just hangs. Have there been any changes to the kernel locking mechanism lately? I've written the the procmail maintainer to see if he had any suggestions, but did not hear back. I don't know what could be causing this, but if anyone has any suggestions for debugging the problem, I'd like to know.
