Apache and MRTG Logs

[sn1tch]

I'm not sure if this is something I need to be worried about, but
after I got MRTG setup on my bsd system I noticed that the error logs
were starting to show this:

[error] [client *.*.*.71] (13)Permission denied: mod_mime_magic: can't
read `/home/sites/ipv4.youthranches.org/web/mrtg/127.0.0.1_2.log'
[Fri Feb 18 13:35:25 2005] [error] [client *.*.*.71] (13)Permission
denied: mod_mime_magic: can't read
`/home/sites/ipv4.youthranches.org/web/mrtg/127.0.0.1_1.log'
[Fri Feb 18 13:35:25 2005] [error] [client *.*.*.71] (13)Permission
denied: file permissions deny server access:
/home/sites/ipv4.youthranches.org/web/mrtg/127.0.0.1_1.log

I chmoded the files 755 but as soon as mrtg updates theold and new log
files they are set back to 640

Thanks
