Erroneous Account Suspension?

[lostcommander]

My account was suspended yesterday for "high system resource usage". I see no signs that this could have been the case. My site is still suffering from a severe lack of traffic, has used almost no bandwidth this month, and has no CRON jobs or any other automated scripts. The virus check said no virii were found. I did have one spam bot register to my forum and make a single post on the 15th, but I do not think this was the cause of the suspension. Could you please either remove the suspension and warning from my account (I have already unsuspended it), and/or let me know what on my account overused (or might have overused) the resources? Thank you very much for your time and support of this great service and community.

Looks as there's a script that uses up a bit of cpu time during processing.
The script is located at: /public_html/trade/index.php

This is part of the log that shows a little what the script was doing at that point:
QUERY_STRING=page=search&CurrencyA=14&GameA=11&Ser verA=2&CurrencyB=21&GameB=11&ServerB=2&sid=383843a dcc21408943566f789e21139e
REQUEST_URI=/trade/index.php?page=search&CurrencyA=14&GameA=11&Server A=2&CurrencyB=21&GameB=11&ServerB=2&sid=383843adcc 21408943566f789e21139e

Thank you very much for your quick reply and for the log entry.

That is one of my pages. I am looking at it now to see what the problem might be. It is a little strange though, since I have not changed any of the pages since last semester.

could be something that temporarily caused execution time to exceed the normal (at least I assume that is why cpu time got over the limit)

I have reviewed the error log for that file and there are several instances over the past month (wait, I had visitors!?! maybe just bot crawlers) on 3 lines between 2 files. They are all related to MySQL. If the MySQL server takes longer than usual to respond, does that trigger the 20-second PHP failure? Could something like that have triggered the overuse suspension?

Also, looking more closely at the log lines you posted - those parameters are from a previous iteration (October 2009 maybe?) of the trade section of my site; page=search no longer exists.

Thank you very much for your help and I will assume for now that a temporary problem was responsible. If this happens again, I will investigate more deeply into the cause(s).
