stucking at run_11_unwrap Initializing flows with MCF algorithm

[03ddd]

Hi everyone, I'm trying to process some Sentinel-1 SAR images using ISCE2 in Linux system, using Ubuntu20.04.6, via virtual box.

Earlier the day, I first tried to conduct run_11_unwrap, but was suddenly killed with :
run_11_unwrap: line 10: 128998 killed
SentinelWrapper.py -c /media/sf_share/sediment/Stacks/configs/co

nfig_igram_UNW_20230806_20230830

So I tried to find out that the problem lies in OOM, but I can't spare more RAM on my virtual machine due to the limited RAM of my physical computer. Then I created a SWAPfile with 8G, added to the original 10G RAM, the total would be 18G. I thought it was enough.

Now, I'm conducting run_11_unwrap again, and the terminal just looks like it got stuck and won't continue processing for hours. Didn't even report an error, just keep stuck.

The commands used for creating a 8G SWAPfile and the status of being stuck are on the pictures.

Can anyone kindly tell me how the problem occurs and how to get out of it? Many thanks!
