Limit size of log file from syslog

Hi,

I'm using Linux 2.6 cross compiled for a embedded powerpc.
Earlier we were using busybox syslogd for logging the messages, but as the flexibilty is less, we decided to move to standard syslog.

Now I want to limit the size of the log file (/var/log/messages) to 128K.
I couldn't find any option in syslog.conf file to limit file size of log file, at the same time this option is present in busybox syslog.

Due to flash's size limitation I can't use cron or logrotate.
So, any one please provide a work around to limit the size of /var/log/messages or to make this file a circular one?
Any help is appreciated.

Thanks
Jay

Log::Dispatch::Syslog(3)				User Contributed Perl Documentation				  Log::Dispatch::Syslog(3)

NAME
Log::Dispatch::Syslog - Object for logging to system log. SYNOPSIS
use Log::Dispatch; my $log = Log::Dispatch->new ( outputs => [ [ 'Syslog', min_level => 'info', ident => 'Yadda yadda' ] ] ); $log->emerg( "Time to die." ); DESCRIPTION
This module provides a simple object for sending messages to the system log (via UNIX syslog calls). Note that logging may fail if you try to pass UTF-8 characters in the log message. If logging fails and warnings are enabled, the error message will be output using Perl's "warn". CONSTRUCTOR
The constructor takes the following parameters in addition to the standard parameters documented in Log::Dispatch::Output: o ident ($) This string will be prepended to all messages in the system log. Defaults to $0. o logopt ($) A string containing the log options (separated by any separator you like). See the openlog(3) and Sys::Syslog docs for more details. Defaults to ''. o facility ($) Specifies what type of program is doing the logging to the system log. Valid options are 'auth', 'authpriv', 'cron', 'daemon', 'kern', 'local0' through 'local7', 'mail, 'news', 'syslog', 'user', 'uucp'. Defaults to 'user' o socket ($) Tells what type of socket to use for sending syslog messages. Valid options are listed in "Sys::Syslog". If you don't provide this, then we let "Sys::Syslog" simply pick one that works, which is the preferred option, as it makes your code more portable. AUTHOR
