[syslog-ng] bit of an issue with logging

[John]

Hi All,

A bit of an issue here.  I'm having syslog-ng create directories when
a new host starts logging to it, which is all well and good.  But, when 
I look in the servers directory there are some directories with logs
in them which surely can't be right!

Is this something I should be worried about?  It does worry me!!
Any ideas why this is happening?

It caused a problem with my newsyslog when it tried to rotate the logs
in the > directory causing my disk to get rather full quickly within a few
days of not rotating.

Cheers,
John
