[Message part 1 (text/plain, inline)]

I tried running 'guix pull' on a VPS running guix and it crashed. The
output said to email the log to this address, so I am.

I'd appreciate any pointers towards a solution; I did a bit of googling
and didn't see how to get unstuck.

Thanks!

These kind of problems are often transient and can be resolved by
trying again.

Anyways, I have a patch to make "guix pull" print more descriptive
error messages (https://issues.guix.gnu.org/50238), which should in the
future help with investigating the cause of these failures, but it
needs a little more work ... (maybe tomorrow)

Greetings,
Maxime.

Unfortunately, I have tried four or five times over the last three weeks
and always gotten this crash.

Do you have enough free space on your VPS?  Or enough RAM memory?

How much is required? I don't see it documented in the man page or manual.

Well, it depends. :-)   Is it because the free space or because of the
RAM?  I mean, what is the value of the free space?   Have you already
succeed with "guix pull" or is it the first time you are running it?

The VPS was created almost two years ago, and 'guix pull' was run many
times, though not in the last few months.

Is there documentation anywhere of what system resources a guix system,
or this particular command, requires? Is there any method for
estimating? It sounds like you're suggesting the requirements have
changed over time. Do running guix systems require more disk and RAM as
they age, or does this undocumented requirement also apply to new
systems?

At this point I'm less concerned about this individual crash bug and
more concerned that running any guix system is unsustainable.

Did you garbage collect “guix gc”?  For instance with the option ’-F 5G’
or this option ’-d 9m’.

Because if you pull again and again, the store is growing.  And
depending on the size your VPS, you can reach the limit of the available
space.

No, I am not suggesting a change.  I am trying to identify why your
setup is failing and emit hypothesis.

You are drawing hard conclusions from some hypothesis when they are just
hypothesis.

Over this 2 years, how many times did you garbage collect?
