[cobalt-users] [RaQ4] Strange behaviour: excess hits, corrupted files, duplicate mails etc.

["Mikael Siirilä" <cobalt-lists@xxxxxxxxx>]

Assistance needed:

We are experiencing strange behaviour on a virtual site running on our 
Cobalt RaQ4. Please see if you can figure out what could be wrong? Also 
please see if you can figure out whether the user could have caused this or 
if its a system issue.

A customer running a virtual site on our RaQ4 reported the following 
problems:

- - -

1. There is a sudden high increase of hits in the statistics (Webalizer) of 
the virtual site. A average usage site has 4+ million hits in a single day 
coming from two DSL addresses both belonging to people maintaining the site.

2. During the same day the disk usage of the site had multiplied from 300Mb 
to 800Mb with no apparent reason. Disk quota had been radically exceeded 
without massive uploads by users or such normal causes.

3. Some website files had lost their rights, they had no longer any group or 
world rights. The user claims not to have altered rights.

4. Several files (jpg) were corrupted and were no longer displayed correctly 
in browsers. They had been uploaded normally via FTP.

5. Recipients of emails have received serveral copies of emails. (We dont 
have raports that any other virtual site on the machine would have such 
issues.)

There are currently approximately 50 virtual sites on the machine. It has 
maximum memory (512mb). We have received warnings of high memory use and 
server load before, but not continuously. What could be wrong? What should 
we look into?
