Proxy service crash with a similar line in "Log" > "<Servername>" > "<Servicename>" > "cache.log":

Error: Too many queued ntlmauthenticator requests (<X> on <Y>)



Your configuration allows squid to use only <Y> authenticator requests. At the moment <X> authenticator requests are queued.

Configure your settings according your network size. At "Config" > "Box" > "Virtual Servers" > "<Servername>" > "Assigned Services" > "<Servicename>" > "HTTP Proxy Settings" > "Access Control" > "Authentication Settings" you have configured a number of "Authentication Worker" - increase these worker until your proxy runs stable.
