More than 20 years ago, I had frequently the same experience with Linux becoming unresponsive.
Then I have stopped using swap partitions or swap files. For more than 20 years I have never used again any kind of swap, on a large variety of desktops, laptops and servers with Linux. I never had again any problem with unresponsiveness.
Nevertheless, I provision all the computers with generous amounts of DRAM, e.g. there are many years since I have last used a computer with less than 32 GB. In these conditions, OOM events are extremely rare.
While there are people who claim that there still exist cases when swap can be useful, I have never seen any evidence for this claim.
