Thanks for the report! I'll set the severity to important for now,
because the package still works nicely for many other users. Not sure
why it's making so much trouble for you..
Because computers hate me :-) I actually have yet another problem with
an sshfs mounted s3ql file system but was trying to get the issues with
my S3 mount resolved first.
but I notice that (like the
last bug you found) this seems related to the handling of unreliable
network connections. In this case there seems to be a temporary problem
with your DNS server which S3QL has trouble coping with.
From a high level perspective, the connection (generally) is pretty
reliable, but I wouldn't notice momentary network issues.
The raw_streamXXX files are from the patch that you applied to the debug
the previous issue. I'd recommend to purge and reinstall both the s3ql
and python3-dugong packages to make sure that you're in vanilla state again.
I forgot about the dugong patch, so I reinstalled both packages, using
the Debian-unstable version for s3ql
If the file system still hangs (or the next time it hangs), could you
follow the instructions at
https://bitbucket.org/nikratio/s3ql/wiki/Providing%20Debugging%20Info to
obtain a Python stacktrace, and attach it to this issue?
This time the file system didn't hang until I attempted to unmount it.
Attached are two log files with the mount and stack trace information.
