Running with this config (only relevant parts shared):

# Rate Limit configuration
rate-limit: 150 # requests/sec
bulk-size: 50 # Max Number of targets to scan in parallel
concurrency: 100 # Max Number of templates to use in parallel while scanning

# Optimizations
timeout: 3
retries: 1
max-host-error: 10
stream: true # start elaborating without sorting the input
scan-strategy: host-spray # Scan Strategy to Use (auto/host-spray/template-spray)

# Debug - Enable only if errors detected
hang-monitor: true

Expected Behavior:

Don get the panic error or handle the error to don't stop the scan

Steps To Reproduce:

scan launched with severity: critical,high,medium,low,info,unknown with 706 hosts
