XTool 2020 (Main Project)

[Wanterlude]

Guys, does anyone know how to fix this?
Game: A Plague Tale Requiem
Files: *.DPC
Xtool: last ver 0.7.0 hotfix
Problem: after unpacking 1 file (28.9gb) xtool goes beyond its allocated memory. (x4)
The picture shows the information from windows resource monitoring. (I have 16 GB RAM)

[External compressor:xtool]
header = 0
unpackcmd = "xtool.exe" decode -t100p -dm20p -sm20p - - <stdin> <stdout>

[External compressor:xtool]
header = 0
unpackcmd = "xtool.exe" decode -t100p -sm20p --mem=20p - - <stdin> <stdout>

In 1 case it happens as shown in the picture. In 2, the memory increase can be seen even in the windows task manager.

arc.ini:

[External compressor:xtool]
header    = 0
default   = -c128mb -t100p
packcmd   = xtool.exe precomp -mzlib -d1 -db -dd5 - - <stdin> <stdout>

-----------------------
upd. (14 may): preflate has the same problem | xtool 0.6.9 - same
-----------------------
upd. (15 may): fixed by 2nd xtool and -dm20p -sm20p parameters.
I think the problem was that I used 1 xtool for both zlib and dedup
