Thanks for the link. I submitted a bug report.

you need to add a bug report- https://store.codesys.com/en/#
my question -> bug report /8 add all information/details.
This is the official way how it will work and come hopefully into the product.

Control Linux SL runtime - segmentaton fault on startup

Also "sudo" does not help.

The situation is extremely disappointing for me. That's why I invested the last hour trying to debug the problem and I found a workaround.
Conclusion: I think it is a bug in codesyscontrol. When reading /proc/stat, a buffer overflow occurs because I am using a machine with 24 CPU cores and the developer of codesyscontrol apparently did not expect /proc/stat to be so large.

Details:
I tried to run condesyscontrol with gdb to find out why it is crashing:

~$ gdb /opt/codesys/bin/codesyscontrol.bin -d 
...
warning: /etc/CODESYSControl.cfg ist kein Verzeichnis.

So it seams, the process crashes while reading something from a file into a buffer, which already contains "cpu22".
Of course, codecontrolsys.bin is a stripped binary, so a stack trace didn't really help me.

(gdb) bt

So I tried strace to find out which file codesys reads from when it crashes.

~$ strace /opt/codesys/bin/codesyscontrol.bin -d /etc/CODESYSControl.cfg

...

So it looks like the programme is crashing while reading from /proc/stat. I checked that file and it also contains the "cpu22" string I have seen in gdb. I'm using a Ryzen 3900 CPU with many cpu cores.

It looks to me like the buffer that "read" uses is not big enough. My first thought therefore: "How can I make /proc/stat smaller"? Of course: Disable CPU cores

Yep, it works.

@Codesys team: Can you fix this bug? I bought a Control Linux SL licence because I wanted to implement automation with a machine vision task on a powerful CPU platform. I have to deliver this project to my customer in a few weeks. I look forward to a fix in a timely manner.

Try instead the command
/opt/codesys/bin/codesyscontrol.bin -d /etc/CODESYSControl.cfg

because CODESYSControl.cfg references CODESYSControl_User.cfg, plus has some additional required settings.

Also try to delete all applications form runtime deploy tool.

Does anyone have a suggestion for me?

I updated to 4.4.1.0. The error message on the command line changed a little bit, but the result is the same: segmentation fault.

Is you Ubuntu system a 64bit version? check by uname -a
could you use 4.4.1.0 version for a test?
