Sudden (unrealistic) Spike in Bandwidth/Traffic Report

We have a customer running Plesk 9.3 who contacted me because Plesk is reporting that one of their customers is 12.9 TB Overused on their bandwidth.

We have software that monitors all traffic to the switch port associated with that server and there are no spikes showing up there. Webalizer statistics for the domain aren't showing any increase either, the only place we see the spike is in the traffic report. Normal usage for this domain is about 150MB per day with the exception of the 12 terabyte spike that showed up in yesterday's log.

Any suggestions on troubleshooting how this may have happened? It sure seems like a "glitch" in Plesk to me, since we can't find any other evidence that the site traffic has increased.
 
It seems to be a fix for 64bit cent Os. But unfortunately my server is 32bit.
 
Why 64bit? It is for 32bit CentOS 5. (cos5x32 prefix).
 
thanks for all ur help..
Sorry am new to plesk.. Does anyone know how to reset the bandwidth for a reseller a/c to Zero?
 
Look at 'ClientsTraffic' and 'DomainsTraffic' tables in Plesk database.
 
We were running into this issue on Debian 5.

I ended up opening a support ticket for this and basically, the issue was due to long requests in the Apache logs. You can check for such requests by running this command:

awk '/; [0-9]+; [0-9]+; [0-9]+; [0-9]/{n++}END{print n}' /var/www/vhosts/<domain>/statistics/logs/access_log.processed

If you see a single request displayed a whole bunch of numbers over and over, then you're probably running into the same issue. Plesk was getting confused and adding up all these numbers in the request, creating an unrealistically high traffic usage entry. Parallels engineers ended up creating a hotfix for the statistics utility in our case, and uploaded the patched version to our server.
