Error message in /var/log/syslog, what does it mean and does it require any action

The error message in /var/log/syslog is: "modprobe: Note: /etc/modules.conf is more recent than /lib/modules/2.4.27-2-386/modules.dep".

It sounds like a warning message, but what exactly does it mean and does it require action on my part. It appears a few times a day in the logfile on a very busy production server.

This means that the modules.conf file has been updated but the modules.dep (module dependencies have not)  i.e. someone manually modified the modules.conf file.
It is possible that you updated a system module that did not require an update of the module.dep file rare but possible.

Was an update applied, kernel?
If an update was applied and if everything is running ok, you can just execute touch /lib/modules/2.4.27-2-386/modules.dep to avoid seeing this error notice until the next update.

Non-kernel updates are applied weekly, however kernel updates are less frequent. I'm pretty sure the modules.conf file was not modified manually, at least not by a human being. Perhaps by another update process?

What triggers this error message, it appears at different times in the syslog file.

When you say that the error appears at different times, do the times correspond to a particular event i.e. a USB device attached?
Try running modprobe -l to see whether the error message appears.
It could very well occur when a specific access is attempted by the kernel that relies on a module.  There is likely an application that is running that every so often probes to see whether there are any changes in attached devices/components.

modprobe -l prints out a list, but does not trigger the notification on the console, nor  does it log anything into /var/log/syslog

I have 'touched' the file as you suggested and the warning message seems to be gone "for now". I'm going to see how this develops. Thanks for the information.
