I just noticed that it is also the case with kern.log:
$ ls -lah kern.log* -rw-r----- 1 syslog adm 178K 2008-11-25 10:49 kern.log -rw-r----- 1 syslog adm 15G 2008-11-24 01:05 kern.log.0 -rw-r----- 1 syslog adm 118M 2008-11-18 09:40 kern.log.1.gz -rw-r----- 1 syslog adm 69M 2008-11-17 11:13 kern.log.2.gz -rw-r----- 1 syslog adm 15K 2008-11-10 22:44 kern.log.3.gz
I think the cause of these large files might also have been waking up with a thread scheduling problem:
