Description of problem:

When I do some testing in bugdev, found that the disk is 100% full. 
Checking the reason, then find the Apache's log (/var/log/httpd/error.log) grows extremely quickly and make the disk 100% full.:
error.log.1 which was "mv" from error.log yesterday is almost 2G.
and error.log is 2.7G now after my testing today.

The 80% error message is the same one:
[Mon Aug 03 16:42:04 2009] [error] [client 127.0.0.1] [Mon Aug  3 16:42:04 2009] post.cgi: Use of uninitialized value $1 in hash element at hwcert.pl line 608., referer: http://localhost/hwcert-xisun1/enter.cgi
