It might be worthwhile taking a look at the program which Matthew
Hagerty wrote called "pgLOGd".

It's designed to get around the need to open heaps of log files, instead
it pipes all the log entries to a single daemon which logs the entries
into a database for later processing.

Not sure how it would work in a virtual domain environment though. :)
