Your swap partition is, very likely, too large. As a rule, your swap

Linux can handle well above 40 GB of swap. I would be surprised if "swap
partition too large" was the reason. My swap is larger than that.
I am always a bot surprised by advice like the ones in this thread. I
have heard and seen this many times.
I am aware that for web-browsing, and other similar activities, using
swap is almost always bad, as it slows the system down.
I typically run programs and scripts without having a good estimate of
their future memory usage, and my computer usage is frequently
RAM-bound, so I try to guess how much I can do within the memory I have
available.
It is not uncommon for me to misjudge the need by a factor of 2 or 3,
and in those cases, I have programs being killed left and right unless I
have enough swap-space.
I would say that being careful with swap-space is important when one has
too small a hard drive, but I have plenty of drives space these days.
Not having my jobs killed is more important to me than saving a few tens
of GB of extra space.
I have just above 40 GB on my current desktop, and when I had influence
over a computer with 64GB RAM, it had quite a bit of swap space.
Mem: 64558M total, 24822M used, 39735M free, 324M buffers
Swap: 184323M total, 25M used, 184298M free, 24238M cached
