OK, none of those left.

SELinux is disabled, always has been and verified off.

Are there any logs other than the HTTPD logs?  There's nothing in the error log, and the access log is already posted.

I tried exporting the QUERY_STRING and running the showgraph.cgi directly but it keeps telling me "Invalid request - no host or service" so I'm not sure what I'm doing wrong.

I'm going to remove the dash from the test name and see if I still get the missing graphs.

Thanks!
