Package: atop
Version: 1.26-2+b1
Severity: grave
Justification: renders package unusable

Since midnight, I don't get any atop logs, which is really annoying to
know what happened a few hours ago. The last file in /var/log/atop is:

-rw-r--r-- 1 root root 3258933 2016-05-01 00:00:01 atop_20160430

and there is no atop_20160501 in particular. According to the atop(1),

       View the contents of today's standard logfile interactively:

         atop -r

but:

zira:~> atop -r
/var/log/atop//atop_20160501 - open raw file: No such file or directory

So, the file should have been there.

With journalctl, I can see concerning atop:

[...]

I can see that this is not the first time I get a "trap divide error"
for atop:

The atop_20160405 is also missing. So, the missing files seem to
correspond to these "trap divide error" errors (a division by 0?).
