I don't see ever growing swap.
You have 3.38GB of swap you could be using.
You have 100MB of swap actually enabled, of which ~80MB is used and 20MB is
free.
That's approximately nothing.

If your swap is a partition, it's a fixed size and can't grow.  So if you
exceed swap the kernel will just kill a process to free up space.  The same
thing will happen if you don't enable swap.

If you want a system with more consistent performance, you can disable swap.
Then everything either fits in RAM or the system kills it.  Then you don't
end up in a disc thrash death spiral.
