Description Marc Muehlfeld 2013-02-22 16:36:18 UTC
I use the following parameters for logging:

log file = /var/log/samba/%m.log
debug pid = yes
log level = 1
max log size = 1000

All logfiles are rotated if they get bigger than the configured size (that's how it should be):

# ls -lh*
-rw-r--r-- 1 root root  12K 22. Feb 16:57
-rw-r--r-- 1 root root   1M 21. Feb 11:43

only the %m.log, is growing without end:

# ls -lh %m.log 
-rw-r--r-- 1 root root 20M 22. Feb 17:35 %m.log

The difference I see is, that yours is a standalone and on all machines 
I have this, are DCs.

Also on DCs, the logs of the clients are rotated. But there's also one 
logfile named "%m.log" (with your config, It would be called 
"rotateme-please-%m.log"). This one contains output from the samba 
process and not from smbd or the child-smbds forked by connecting 
clients, I think. And this one isn't rotated

Problem still exists in 4.1.7.
Setting product / version of this bug report to 4.1.7.

Update: In 4.5.0rc2, the rotation for the log file named %m.log still does not work.
