Re: BufferAppender and CyclicBuffer

[Ken Arnold <ar...@moonhill.org>]

Just catching up here.

I posted a similar thing which you might also want to look at.  For 
reference:

Bug fix	http://marc.theaimsgroup.com/?l=log4j-user&m=102881132725686&w=2
Feedback	http://marc.theaimsgroup.com/?l=log4j-dev&m=102882827915720&w=2

We've been using this successfully in house for some months now.  (Some 
other bug fixes are in there, but it is substantially the same -- will 
post fixes if anyone wants them.)
