There are 2 potential fixes, one is to keep open the logfile once it is 
opened, the other is to log via a separate running process (like syslog).
There was talk of having a separate helper process to solve various 
netatalk issues including this.  This would be my preferred solution.

However, when I first wrote the logger I though about keeping FILE's 
open, but abandoned the idea, because a crash of afpd mean that the FILE 
cache buffer was lost, so you never saw what caused the problem.  I 
tidied up that bit of code some time last year, by calling fflush where 
I would have called fclose.  The new code is switched on my defining 
KEEP_LOGFILES_OPEN, which should be on by default.
However, it still opens the file as whichever user the process is, when 
the file is opened.  I assume this is the uid that called afpd in the 
first instance, which should be root.

Like I say I'm not sure why you're still getting this, assuming you have 
the current patches to the logger (which I think are in 1.6 as well as CVS)

Indeed it is a hack, but so is keeping open the log file and fflushing 
it every time someone logs something.  I prefer the chmod a+w hack, it 
should be quicker.
