Sonarr becomes unresponsive during file transfer

Sonarr version (exact version): 3.0.6.1342
Mono version (if Sonarr is not running on Windows): 6.12.0.107
OS: CentOS 7
Debug logs: https://drive.google.com/file/d/17OLqLRuX2W0gknKhFsMXGVaf3elwTWnk/view?usp=sharing
Description of issue: I keep having issues where sonarr is hanging when there are multiple files to transfer. I can see if transfer 1 or 2 via iftop but the whole time the UI doesn’t respond and eventually to whole process dies. I see things like this in dmesg to go along with the attached debug logs.
