Hi,

A client is running an e-Commerce site using the superb CGIDEV2 toolset. 
It's running on the Apache server using the current downloadable version 
of CGIDEV2 and we're up to date with cumulative PTFs.

Once or twice every day one or several of the Apache server instances 
crash with an application error. The other server jobs carry on working 
fine servicing other jobs so to counter it in the short term I added a 
reply list entry to dump the jobs automatically.

Does this error imply that somebody is trying to hack the site by 
appending a piece of script to a form request or is it more likely to be a 
bug in our application?

Here's an extract of one of the job logs:
