bioperl-live | Core BioPerl 1.x code | Genomics library

I have a development laptop (Mint 19.3), and a test server (Ubuntu 18.04.4 LTS).

The laptop is Docker version 19.03.5, build 633a0ea838, the server is Docker version 19.03.12, build 48a66213fe

I'm running Python 3.6 code inside the container, which uses subprocess (code below) to create an sshfs mount to a third server, after which the python code walks through the mounted directory.

Everything works fine on my development laptop. But on the server, the directory mounts (and is seen with the mount command) however cd'ing into the directory just hangs, and the Python code's subsequent walk just hangs. (NOTE: The python code never crashes or errors out. It just hangs forever.)

HOWEVER, if I manually use the same sshfs command at the container's command line, the directory works fine.

I'm at a loss as to how to troubleshoot this.

OK. Since the Python code uses subprocess, the sshfs mount is obviously available to any terminal windows that wants to use it.

I have tried accessing the mount from a new terminal window inside the container, but when I cd to the mount - the window just freezes.

Well, I left everything sitting overnight - and now when I try to cd into the mount ... it works. It's like the mount has to sit for hours before it will work.

Any ideas?
