Gnu parallel rsync hanging indefinitely

To be clear, I am running this exact command(variables changed) in a gnu parallel setting:
/usr/bin/parallel -q -j20
rsync --recursive -av -e ssh -oCompression=no -x -T
-oUserKnownHostsFile=/dev/null -oConnectTimeout=15
-i ssh_key -l some_username --chmod=Dugo+rwx,Fugo+rw
--files-from /some/base/dir somehostame:/some/other/dir
This consumes about 50 files(containing list of file/directory names for rsync), across 20 workers through gnu parallel. I ran the above yesterday night, and I came back to work to see that there is still 1 rsync job, hanging:
rsync --recursive -av -e ssh -oCompression=no -x -T -
oUserKnownHostsFile=/dev/null -oConnectTimeout=15
-i ssh-beta-secdata-20180515t213639 -l diskmaker
--chmod=Dugo+rwx,Fugo+rw
--files-from ./some_filelist /some/base/dir somehostname:/some/other/dir
So to be clear, some_filelist is a list of directories I want to do rsync in.
I'll take the files from the base(as if chroot'd) from /some/base/dir to a remote directory somehostname:/some/other/dir.
So there are like, 500 jobs that parallel pulls from. I analyzed each file list, and there's nothing special about this ./some_filelist; standard 200 files from an rsync dryrun.
Does anyone have diagnosis for this problem? I am completely lost to how this could happen. I can post more snippets if required.

can you list what files the hanging process has open (lsof -p pid), and what syscall it is hanging on (strace -p pid).

Does it work, if you run the hanging command on the command line? Can you try splitting./some_filelistand see if some parts work find? Is the the same part that is hanging if you useparallel --shuf?

Hope you make sure differentrsyncprocesses do not read/write to the same dirs.
