Mike, Thanks for the report. I have not seen this, but from digging into the code, it looks like it could happen if a Nsock timer (such as is created in stdnse.sleep) is canceled in such a way that still fires the sleep callback function. I can't really see a way to make that happen, but I'd guess it has something to do with host timeouts. I see a few different ways ahead: 1. In the meantime, if you are using -T5 and running lots of scripts, increase your host timeout from the default of 15 minutes, since you probably don't want it to timeout anyway. 2. We can add an additional condition to the assertion so that NSE_STATUS_CANCELLED is valid, too. This would result in the thread which called the cancelled sleep to be resumed, so I don't know if that's what we want either. 3. We can dig into the specific conditions which caused this crash and correct the underlying problem. If you want to help with this, please let us know the exact command line you used, whether you can reproduce the crash, and any information (open ports, services, etc) about the target that may be relevant. Thanks again! Dan On Sun, Feb 8, 2015 at 10:14 PM, Mike . <dmciscobgp () hotmail com> wrote:
