Someone will no doubt correct me if I'm wrong, but I don't
think there's a plugin like this.

Consult your web server's log to see what requests were
being serviced when this error occured. It may be related to
DDI_Directory_Scanner.nasl (plugin #11032), which makes
close to 800 requests in attempts to locate various common
directories on a web server, and/or the number of
web-related plugins being run simultaneously. Regardless,
you may want to tweak the settings for MaxClients and/or
MaxRequestsPerChild are rather low on that target to better
handle higher loads.
