Re: locks and shutdown policy; was Re: stale lockfile on fetchmail.
Andrew, Ron, Tzafrir and others, Thanks for the clarifications. At Mon, 11 Feb 2008 19:14:58 -0800 as-w ... fetchmail being killed in a nasty way ... We're still not exactly certain how the stale lock comes to exist but ... At Tue, 12 Feb 2008 09:11:39 + tc fetchmail is a daemon, ... tc fetchmail cleans that stale lock on (its) startup. System startup or my login invoking a fork of fetchmail? The user can remove the stale lock but a daemon should be able to run without intervention. Seems that the maintainer should be examining design of the locking mechanism. Reimplementation may be necessary. Unless we've overlooked something, this justifies a bug report. Thanks,...

I think this is more likely an issue of fetchmail being killed in a nasty way (kill -9 ppid of fetchmail) or dying due to some other problem. A signature.asc Description: Digital signature
