Well, perhaps your command queues too much frame and that is bad.

Perhaps?

ffmpeg -i source.mkv -map 0 -filter_complex "telecine, setpts=N*1001/30000/TB" -codec:v libx265 -x265-params crf=20:qcomp=0.60 -codec:a copy -codec:s copy "with both telecine and setpts.mkv"

What does "...perhaps your command queues too much frame" mean?

Out of curiosity, have you tried looking at the file with an mkv
analyzer like MediaInfo, Elecard's
analyzer* or maybe another one? (Is there metadata towards the end of
the file containing junk info?)

How does it behave if you drop the minterpolate or one of the other
filters, output to a null file,
or use a different output codec? (Anything to try isolating the problem.)

If rising memory allocation and rising swap commit indicates a memory
leak, then the telecine filter
has a memory leak.

**WRONG**

OHMYGOD! The problem isn't telecine. The problem isn't setpts. The problem
is telecine + setpts in
combination!

**CORRECTION**
If rising memory allocation and rising swap commit indicates a memory
leak, then the combination of
telecine and setpts filters provokes a memory leak.

My trouble packet is 'telecine+setpts memory leak.zip'. I can't put it in
dropbox because dropbox
has now added a 100 MB limit in an attempt to force me to pay.

'telecine+setpts memory leak.zip' is 328 MiB.

With no way to get 'telecine+setpts memory leak.zip' into the developers'
hands, I guess all my
efforts will go to naught.
