Hi,
I was looking at top on the hydra-guix-129 node, which runs nar-herder,
and saw this:
--8<---------------cut here---------------start------------->8---
4772 nar-her+ 20 0 28.9g 11.5g 100.0 6.1 55,55 S .nar-herder-rea
--8<---------------cut here---------------end--------------->8---
11.5 GiB of memory seems a bit excessive, no? Its cumulated processing
time is also at the top of the table, and it seems stuck at 100% of CPU
usage.
Is this expected of the nar-herder, or has it gone awry?

Thanks,
Maxim

I think hydra-guix-129 was running an older version of the nar-herder,
so I've updated it and I think that's improved the situation.
I've just reconfigured the machine to use a specific commit at the
moment, but it would be good to bump the commit that the Guix package is
using.

The situation appears unresolved; c.f. `top' output on hydra-guix-129:
--8<---------------cut here---------------start------------->8---
62775 nar-her+ 20 0 903.7g 93.9g 0.0 49.8 22,44 S `- fibers 0
--8<---------------cut here---------------end--------------->8---
It's gobbled up half of the memory of the machine so far, and will
probably keep growing slowly.
Perhaps the machine should be reconfigured & rebooted, as its generation
appears to be from Nov 23. It's been up for 41 days.

This has since been resolved; it currently uses 675.6 MiB on
hydra-guix-129.
Thanks, Christopher!
