I'm using a RasPi 3B for various Ham Radio projects which all appear to be working well until I open the Chrome web browser with perhaps two or three tabs open. None of it with particularly heavy CPU use - maybe 10-20% peak. The RasPi completely freezes and the only solution is to power off and then re-start.
I've read of similar issues, some of which point to limited swap space as being the issue.
Is this the probable cause and if so how can swap space be increased with an already installed and running system?
Also I've noticed on the ModMyPi Forum that similar issues have been found, which have resulted in the RasPi being replaced under warranty as being faulty.
Could this be the case with mine and how does one obtain a replacement, please?
Many thanks in advance.
