Solution

Open webmin, goto webminstats and open the module “Disk”. Then click on the link “configure module”. Scroll down until you see the list with all watched filesystems. Deactivate the list-entry “/proc/bus/usb” or simply delete it.

After upgrading the webmin module “Webminstats” the cron-job started to send every three minutes an eMail like this one:

Solution

The problem was only solved after I disabled the cronjob, then deleted the module (first make backup of /etc/webmin/sysstats/modules/ !!). After I reinstalled the same version of Webminstats and copy back the backup, the error didn’t appear again (of corse you have to open the webminstats-page at least once for scanning an to reactivate the cronjob).

It seams that is problem started after I made an update of webmin and webminstats. But on other machines I did the same update without receiving errors.

In a previous post (date 2007-10-06) I described how to install webminstats on your debian-system.

On most servers I always got following error message as a jabascript alert when loading the webminstats module-page (https://<servername>:10000/sysstats/):

missing library LWP : can not get sourceforge versions list

You can solve this problem in two ways:

• Easy one: Deactivate the build-in update check of webminstats. Goto “Module Config” on the module-page and set “0″ to the textfield “check update” and save it.
• OR: Download the missing library called “libwww-perl”. To do that, run “apt-get install libwww-perl” on the console.
