Hi, John. I didn't see a followup to the list confirming whether "Thorough
tests" was the culprit in your Citrix server crashes. We're currently using
Nessus to scan some hosts at my company and I was considering turning on
"Thorough" because for several of the https servers we get:
The remote web server is very slow - it took 90 seconds to execute the
plugin no404.nasl (it usually only takes a few seconds).
In order to keep the scan total time to a reasonable amount, the remote
web server has not been tested.
If you want to test the remote server, either fix it to have it reply to
Nessus's requests in a reasonable amount of time, or set the global
option 'Thorough tests' to 'yes'
Nessus ID : 10386
but since some of them are running Citrix, I'm wary of turning on "Thorough"
if it's likely to DoS the servers.
