Summary0006960: System Run Away while working with GVM 20.8
Description

System run away while working with GVM 20.8 which consumes all RAM and fills up complete swap space. In this situation complete system is inaccessible.
Only hard reset would bring system out of this state.

Steps To Reproduce

In my case I have a scan with about 2500 results in a single report.
Then user should go to report page for this specific scan and switch to the results tab.
Then he must reload the page/tab several times by adding filter directives.
Reloading (i.e. adding a new filter directive) should be done while results page is still loading.

Additional Information

Bug 0006763 is still there, but with GVM 20 and PostgrSQL 13.

It seems, that old database searches are still running (the page is still loading) and new searches are added to them.
After a while all system ressources are consumed from old, no longer needed searches.

I think we need an additional function which interrupts old, no longer needed searches when the specific user is starting a new search by changing filter directives.
Or, if interruption of old, no longer needed searches isn't possible, the user must not be able to do anythin new within UI until current action, i.e. the search, is finished.

I was able to get a result of top short before the run-away:

It's a matter of some seconds. Now we see that gsad is consuming the memory and filling up swap space. Does we have some kind of memory leak?
