pingsweep error

[Brian Dao]

I've got a report from Chris Matuszewski, stating that the PingSweep is generating an error everytime he runs it.  PingSweep is one of the module that I have changed its behavior compared to the v1.85.  In v2.15, the free threading model is used to speed up the application performance and as such it's using more system resources.  What compounded the problem was that Chris was sweeping a /21 block (2048 IP's) and the default setting only using 255 threads.  So what we have is [probably] 255 guys trying to compete for 2048 jobs and probably stepping on one another while doing so. 
 
The root cause has yet to be identified, but I think it's due to the way the screen is painted to update the results or the threads stepping on top of one another causing memory fault.A quick resolution for this is to update the default setting from 255 to 2048 threads.  Press F5 to bring up the Settings window, click on PingSweep tab, find 255 and change it to 2048 and click Save.  This will fix the error while pingsweep a block of 2048 addresses or less but it will not fix the issue for good.
 
I'll see if this can be addressed in the next release.
 
Regards,
Brian

I've got more reports sent in on this error.  As expected, the more threads are assigned to run the pingsweep, the more system resources are consumed by Pinkie.  So this temporary solution might not work for everyone.

A work around is to break up larger subnets into smaller ones.  I find that sometimes, I can get /22 or /21 to work.  For most users, it's probably save to go with a /23 subnet.

I'll bump the priority for this one up and try to get it fixed asap.

I always seem to run across an error when copying the sweep to the clipboard. I can drive on with 'Continue' and still paste the results, to it must be a minor error.

Not sure if this helps, but here is the 'Details' from the error:
