logrotate won't finish, high cpu usage

[<manuel@mhofer.eu.org>]

Hi!

recently i've been experiencing problems with logrotate, each time it runs
it 
gets kinda stuck and eats up the systems cpu for days without finishing (i 
don't have that many/big logfiles to rotate)

the output of "logrotate -d -v /etc/logrotate.conf" just stops at "reading 
config info for /var/log/btmp"

the logrotate configuration for /var/log/btmp looks like this:
> /var/log/btmp {
>    missingok
>    monthly
>    create 0660 root utmp
>    rotate 1
> }

when i run strace on the logrotate pid i get the following message
appearing 
over and over again..
> stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2211, ...}) = 0

logrotate is running in a linux-vserver-guest
version: logrotate-3.7.1-5
kernel: 2.6.26-2-vserver-686 #1 SMP Wed Feb 10 10:39:33 UTC 2010 i686 
GNU/Linux

i can't really tell what time it has stopped working and what changed at
that 
moment, but it has been working for a while before.

thanks in advice

regards,
