Comment (by jreed):

 I still have a problem:


 Some log files still out of order:
 {{{
 -rw-r--r--  1 root  reed  1050197 Jun  3 11:35 bind10.log.1
 -rw-r--r--  1 root  reed  1049479 Jun  3 13:03 bind10.log.13
 -rw-r--r--  1 root  reed    22216 Jun  3 13:04 bind10.log
 }}}

 The last two lines in the .13 log file are:
 {{{
 2013-05-30 23:27:54.052 DEBUG [b10-zonemgr.zonemgr/11742]
 ZONEMGR_REFRESH_ZONE refreshing zone foo. (class IN)
 2013-06-03 13:03:16.463 DEBUG [b10-cmdctl.cmdctl/12565]
 CMDCTL_SEND_COMMAND sending command shutdown to module Cmdctl
 }}}

 For some reason "DEBUG [b10-cmdctl.cmdctl/12565] CMDCTL_SEND_COMMAND" was
 sent to wrong destination.
 And see this inode:

 {{{
 1630925   2112 -rw-r--r--    1 root              reed
 1049479 Jun  3 13:03 /home/reed/work/isc/bind10/log/bind10.log.13
 }}}

 And from fstat (same inode):
 {{{
 root     python3.3  23304    8 /        1630925 -rw-r--r--  1049479 w
 root     python3.3   6330    7 /        1630925 -rw-r--r--  1049479 w
 root     python3.3   7269    8 /        1630925 -rw-r--r--  1049479 w
 }}}

 Those three PIDs that have old log file still opened are b10-stats-httpd,
 b10-ddns, and b10-cfgmgr.

 This is with log4cplus-1.1.0.

 Using the trac1622 branch.
