The only problem is that they tend to time out before they get a chance to do anything. Brandon said that after one round of scanning with more than 300 script threads running, in the next round NSE locks immediately. Could something about timing out scripts be corrupting the Lua state? The problem goes away when r11122 is reverted. That was the change that made use of a persistent Lua state.I need more information than NSE locking up on the second scan to determine the cause. As far as I know Brandon hasn't had this problem anymore after I corrected the threads improperly finishing because of time outs.
Reverting r11122 kept the problem from propagating to later NSE scans but as Patrick mentioned, properly handling thread timeouts completely eliminated the problem.
