Good morning!

RHEL6/CentOS6 released an httpd update last night:

Aug 25 04:05:35 Updated: httpd-tools-2.2.15-47.el6.centos.i686
Aug 25 04:05:40 Updated: httpd-2.2.15-47.el6.centos.i686
Aug 25 04:05:41 Updated: 1:mod_ssl-2.2.15-47.el6.centos.i686

This morning both our bw & lat boxen httpd logs (which I check for badness 
= malicious poking) are FULL of errors eg

/var/log/httpd/ssl_error_log:[Tue Aug 25 08:33:55 2015] [error] [client 
128.142.136.248] Premature end of script headers: index.cgi
/var/log/httpd/ssl_error_log:[Tue Aug 25 08:34:55 2015] [error] [client 
128.142.136.248] Premature end of script headers: index.cgi
/var/log/httpd/ssl_error_log:[Tue Aug 25 08:35:55 2015] [error] [client

Trying to get to the toolkit url ends up at error

And in fact /var/log/perfsonar/web_admin DOES NOT EXIST! (presume: it used 
to! - I could be wrong about that?)
