Comment (by jreed):

 This problem still exists with log4cplus 1.1.0 which is said to fix this
 problem. I will report upstream.  Here is the example from production n10
 server:

 {{{
 %ls -ltr /var/log/bind10/ | tail
 -rw-r--r--  1 root  wheel   400705 Oct 30 21:30 bind10.log.8
 -rw-r--r--  1 root  wheel  1048681 Oct 31 06:00 bind10.log.1
 -rw-r--r--  1 root  wheel    82692 Oct 31 06:00 output.log

 -rw-r--r--  1 root  wheel   400637 Oct 31 13:04 bind10.log.7
 -rw-r--r--  1 root  wheel   144156 Oct 31 13:04 bind10.log.6
 }}}

 Multiple log files still written too. Now all out of order. fstat shows
 multiple processes have different bind10 log files open.
