svnsync creates big log files

Hi, I am experimenting with svnsync with a repository that has a lot of
changes. I found that svnsync creates very large log files in
access_<date>.log. Is there a way to turn off this logging? I find that the
disk space consumed by this log file is really big.

Thanks for any help.

My environment:
OS: Centos 5.5 on an i386
Software: CollabNet Subversion 1.3.0-1621.49 (hence the svnsync comes with
this)
