Hey Efraim,

Efraim Flashner <efraim <at> flashner.co.il> skribis:

> I got a test failure on powerpc-linux in tests/services/log-rotation.sh.

The failure looks like this:

--8<---------------cut here---------------start------------->8---
+ herd -s t-socket-5219 stop three
++ file_descriptor_count
++ ls -l /proc/5229/fd/0 /proc/5229/fd/1 /proc/5229/fd/10 /proc/5229/fd/11 /proc/5229/fd/12 /proc/5229/fd/13 /proc/5229/fd/14 /proc/5229/fd/15 /proc/5229/fd/16 /proc/5229/fd/17 /proc/5229/fd/18 /proc/5229/fd/19 /proc/5229/fd/2 /proc/5229/fd/21 /proc/5229/fd/22 /proc/5229/fd/23 /proc/5229/fd/24 /proc/5229/fd/25 /proc/5229/fd/26 /proc/5229/fd/3 /proc/5229/fd/4 /proc/5229/fd/5 /proc/5229/fd/6 /proc/5229/fd/7 /proc/5229/fd/8 /proc/5229/fd/9
++ wc -l
+ test 26 -le 22
--8<---------------cut here---------------end--------------->8---

No idea what could be causing this.  It would be great if you could see
if this is reproducible, for instance by running:

  while make check TESTS=tests/service/log-rotation.sh ; do : ; done

from the failed build tree.

If it is, you could also try with this patch, to get more info:
