It's impossible to tell with the amount of info you provided. That's
why
there's a 'bashbug' script alongside bash to generate a useful bug
report
template.
Provide:
- bash version: bash --version
- OS name and version: uname -a
- The contents of the run.sh file
- If possible also the su version (in my case it doesn't have a
version flag,
but it's part of the login package).
- The output of running said script, with 'set -x' enabled
You might not be running bash at all, since you didn't explictly
called
/bin/bash, instead letting su run /bin/sh, which could be dash, or
any other
shell.

Oh, didn't know this script exists, thank you.. ;)
Here are some more information:

"Haussteuerung" is a compiled mono executable.
Information about the "login" package:
login:
Installiert: 1:4.1.5.1-1
Installationskandidat: 1:4.2-3
Versionstabelle:

Packages
*** 1:4.1.5.1-1 0
100 /var/lib/dpkg/status
When executing run.sh with the -x parameter the output is only
+ ./Haussteuerung
And /etc/rc.local prints:
sudo /etc/rc.local
+ alias ls=ls --color
+ echo 0
+ exit 0
+ su cubie -c (cd /home/cubie/Haussteuerung/Haussteuerung; ./run.sh)
-s /bin/sh
Output from htop (the first process has a cpu usage of 100%):

2199 cubie 20 0 44168 15484 7552 R 101. 1.7 11:45.44 /usr/bin/cli

When running run.sh directly in the terminal the cpu usage is at 2%.
The "Haussteuerung" executable works correctly in both cases.
I hope this information helps.
