Borg: `borg list` or `borg prune` hangs

borg list usually does not hang, but if the ssh connection is stalling or disconnected, it can be caused by that.

It could be also that the borg server is very busy with other disk or network I/O, so borg list comes a bit short.

investigating a bit further, not just the list hangs, but prune too.
And it just doesn't answer anymore.
It looks like an ssh issue then. On this server, there is memory available, cpu is around 10%, just there is no swap available. can it be the issue?
Is there a timeout on the ssh command? Or is there an option to set it? (I searched quickly the doc, didn't find it)

In general, borg needs enough memory to load some indexes and caches into memory (and they can be huge if your repo is huge, there is a formula in the docs to estimate memory usage). If borg runs out of available (virtual) memory, you'll get a MemoryError exception.

If you don't have on-disk swap available, the slow down can not be caused by on-disk swapping activity.

So I guess you have a network or ssh issue.

I am closing this for now as this is not actionable.

Reopen if you have more information, esp. when it points to a problem within borg.
