logrotate issues

[mmanjrekar]

Hi,

i have a Debian server which was properly rotating system logs on weekly basis up until 13-11-2010, post which it has suddenly stopped doing it on weekly basis and is appending logs to the same file. any clue why it might be happening suddenly?
my problem is that logs are not getting rotated.

Debian 2.6.18.dfsg.1-24 ---------- Debian 4.1.1-21 ---------------------- Linux version 2.6.18-6-amd64
---------------------------------------------------------------------------------------------------------------------------
cat /etc/logrotate.conf

# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
#compress

# packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp, or btmp -- we'll rotate them here
/var/log/wtmp {
missingok
monthly
create 0664 root utmp
rotate 1
}

/var/log/btmp {
missingok
monthly
create 0664 root utmp
rotate 1
}

# system-specific logs may be configured here
