Zap Slows down then becomes totally unresponsive like its being starved of resources and i have to kill the pid to get it to respond again. thing is there are plenty of resources to go. my machine isn't a beast but there are 7 cores and 24gb of ram.
First i put it down to resources as i had just run ajax spider and that can be intensive.
I then rebooted machine and opened the task manager (kali linux)
Ran the fuzz attempt again it was skills assessment and i was fuzzing http://targetip:port/FUZZ.php and i was using directorylist2.3-big.txt in the FUZZ param.
Cpu didnt go above 20% and ram not over 30% and zap unresponsive if i would mess with it too much while unresponsive (click 50 different buttons to get it to do differnt things ) then cpu would increase because its having trouble responding in first place and they are all building up in a que.
otherwise it will stay unresponsive till it turns off attack on its own at whatever percentage it cant continue or i get bored of waiting for it and kill it.
it also happened on a previous assessment (different target) but that time i attempted to fuzz 2 prams at same time resulting in 5m+ different payloads and same thing between 250k attempts it would just slow to a crawl and become unresponsive or finish the attack at 7% and give no exit code or reason for stopping. i put that down to resources.
If it was the target and i was hitting it with too many requests that usually affects just the target as its the one having problems responding but i just dont see why zap would become unresponsive if that was the case.
