[leafnode-list] Lock file troubles.

[Ben Hyde <bhyde@xxxxxxxxx>]

Short form:

The short form of the following story is I am on FreeBSD 3.1 and
running 1.9.2 because 1.9.4 won't compile.  Fetch doesn't work, I get 
logs entrys about the lock file every time I run fetch, but I can see 
nothing wrong with the lock file.  

I just subscribed (yes I read big chunks of the archives) to this list
, so please CC me (just to be sure).

Very Long form:

I have been running leafnode plus mail2leafnode for many months
on my personal, but 24/7 connected, machine.   From time to time
I would get messages in my log files about a problem between fetch
and a lock file.  In most cases I believe this was because my
crontab would lauch an additional fetch before the previous
one would finish.  Occationally this lock file would appear
with no process still apparent and I would delete it.

At one point it stopped fetch additonal news entirely.  Mail injection
kept working.  After about a month I looked into the problem and was
able to resolve it by running fetch with -f (i.e. "Force rereading of
whole active file... ".

Given these problems I decided to upgrade to a newer version.
So I downloaded leafnode-1.9.4, but it fails to compile on
FreeBSD.  It had warnings, which I poked at until they
went away.  But a fatal errors around "extern long int timezone;"
made me loose heart.

I then downloade the FreeBSD package with a prebuilt version
in it.  That installed and ran just fine.  It announces 
  200 Leafnode NNTP Daemon, version 1.9.2 running (etc..)
when you connect to it.

Then I had a power failure, afterward I now get this:
  ... fetch[9948]: unable to open lockfile: 2 No such file or directory
every time fetch runs.

Seems like an ovious problem but I'm entirely stuck.

    zap# strings /usr/local/sbin/fetch | grep lock
    /var/spool/lock/news/fetch.lck
    Removing stale lockfile.
    Removing stale lockfile: pid %d
    lockfile %s exists, abort ...
    lockfile %s exists, abort ...
    unable to read lockfile %s, abort ...
    unable to open lockfile: %d %m
    Could not open lockfile %s for writing, abort program ...
    Could not open lockfile %s for writing: %m

So It would appear the lock file is named: "/var/spool/lock/news/fetch.lck"


But it doesn't exist.

    zap# ls -l /var/spool/lock/news/fetch.lck
    ls: /var/spool/lock/news/fetch.lck: No such file or directory

And the directory seems to have the approprate protections:

    zap# ls -ld /var/spool/lock/news/
    drwxr-xr-x  2 news  news  512 Jul 26 12:21 /var/spool/lock/news/

Well where is what I'm running on:
  zap# uname -a
  FreeBSD zap.... 3.1-RELEASE FreeBSD 3.1-RELEASE #3: Sun Mar 21 23:39:27 GMT 1999 ...

Maybe somebody can see what this truss output is telling me.

  Any help most welcome. - ben.
