Apparent Hack attempt filling partition

[Steel City Phantom]

It seems that on friday i had some kind of hack scanner hit one of my 
servers.  it went thru the website looking for scripts, i believe it was 
my hosting company that did it with their vulnerability scanner.  The 
problem is that for some reason, the server was kicked into a loop 
failing on a perl script that eventually filled the /var partition with 
a 1 gig error log file and brought mysql down for lack of temp space to 
run some queries.  here is the last snip of the log before it started 
repeating the can't open perl script for 1 gig of file.  anyone have any 
ideas what could have caused that? 

the server is running PHP Version 4.3.9, Apache 1.3.33 on bsd 4.10 R2P
