Comment 30 for bug 115774

I've been lucky enough to never experience this bug on my machines, but I'd like to provide my 2 cents about what could cause the issue.
The log rotation system seems to be configured to rotate once a day:

-rw-r----- 1 syslog adm 125K 2011-09-13 17:15 syslog
-rw-r----- 1 syslog adm 86K 2011-09-13 07:40 syslog.1
-rw-r----- 1 syslog adm 3,7K 2011-09-12 07:45 syslog.2.gz
-rw-r----- 1 syslog adm 3,9K 2011-09-11 08:05 syslog.3.gz
-rw-r----- 1 syslog adm 5,0K 2011-09-10 07:35 syslog.4.gz
-rw-r----- 1 syslog adm 4,5K 2011-09-09 08:00 syslog.5.gz
-rw-r----- 1 syslog adm 4,5K 2011-09-08 08:05 syslog.6.gz
-rw-r----- 1 syslog adm 6,9K 2011-09-07 08:00 syslog.7.gz

(this is from my personal machine)

If the rotation takes place once a day regardless of size, the logfile can grow very big if there are many processes which generate a lot of "noise".
