Hello, i am running the latest version of w3af agains the owasp benchmark (https://www.owasp.org/index.php/Benchmark) but only for XSS. So i only enabled xss audit with console script, like it follows:

#Configure HTTP settings
http-settings
set timeout 30
back
#Configure scanner global behaviors
misc-settings
set max_discovery_time 20
set fuzz_cookies True
set fuzz_form_files True
set fuzz_url_parts True
set fuzz_url_filenames True
back
plugins
#Configure entry point (CRAWLING) scanner, add into ignore_regex the test cases you don't want to audit
crawl web_spider
crawl config web_spider
set only_forward False
set ignore_regex (.*(cmdi).*|.*(crypto).*|.*(hash).*|.*(ldapi).*|.*(pathtraver).*|.*(securecookie).*|.*(sqli).*|.*(trustbound).*|.*(weakrand).*|.*(xpathi).*)
back
#Configure vulnerability scanners
##Specify list of AUDIT plugins type to use
audit xss
##Specify list of GREP plugins type to use (grep plugin is a type of plugin that can find also vulnerabilities or informations disclosure)
##Specify list of INFRASTRUCTURE plugins type to use (infrastructure plugin is a type of plugin that can find informations disclosure)
#Configure reporting in order to generate an HTML report
output console, xml_file
output config xml_file
set output_file /tmp/OwaspBenchmarkXssW3af.xml
set verbose False
back
output config console
set verbose False
back
back
#Set target informations, do a cleanup and run the scan
target 
set target https://localhost:8443/benchmark/xss-Index.html
set target_os unix
set target_framework java
back
cleanup
start

This benchmark have hundreds of test cases so it takes a long while to spider and start discovering new vulnerabilities. But there is a moment that suddenly show the message: pthread_cond_wait: Resource busy and it doesn't continue any more. Any guesses??

Uh, that's one ugly bug to identify the root cause.

Haven't seen anything like that in the past and nobody reported something similar either.

Usually I recommend disabling parts of the framework until understanding what might be causing the issue. In your case I would disable 50% of the plugins, run the scan, check if the issue is there, then disable more plugins, etc. until you can pinpoint the minimal configuration that triggers the issue.
