7zip multithreading deadlock on ~100Gb files
Posted: Nov 9th, '20, 22:22
Hello, 7zip freezes on compressing big file when I specify -mx=9 -myx=9. If I call strace on running processes, I see single futex syscall in every process. If I specify -mmt=off, I face great decrease of compression speed, but no freeze. How can I troubleshoot that? 5.9.6-desktop-1.mga8, 7z 16.02 2016-05-21. Ryzen 5 3500X, 16 Gb RAM.
