About after 16 hours of well execution, the runtime stops.
In the codesyscontrol.log I can see the line:
#### Exception: *EXCEPTION* in CommCycleHook <IP>0x76db7d6c</IP><BP>0x1000</BP><SP>0x73f63d38</SP>
And just a few seconds later, the runtime stops.
Like Edwin Schwellinger adviced in this topic (it seems to be a similar issue?) https://forge.codesys.com/forge/talk/Deutsch/thread/c8bb956c6b/?limit=25#3484 I tried to run Codesys manually via SSH.
But the problem is that after 2hours it stops because of "Demo mode"... And my issue is only after about 16 hours of run... So I can't see any problems within the 2 hours...
I also tried the second option (edit the CODESYSControl.cfg and create the /etc/default/codesyscontrol to enable debug logging) but my /tmp/codesyscontrol_debug.log remains empty.
I have no idea of why I have this CommCycleHook Exception, neither what it means...
And I cannot have more information in the log files...
Please, do you have somme advice for me ?
Thanks.
Have a nice day.

but there is no difference on license if you start manually or automatically.. so it should run more then 2h
and which system i s it - Linux SL oder Raspberry Pi...or?

So effectively, Modbus, OPCUA and Webvisu stopped after 2 hours, but my application continued.😉
Finally, with this "debug" mode I had much information about my problem: it tells that I have too many files openned.

So I supposed there 2 options : There is a limit on the maximum files simultaneously openned in codesys I reached this limit on the raspbian OS directly
Do you know if there is a limit in the Codesys runtime on the max number of oppenned files? And if there is one, is it possible to override it ?
Meanwhile, I will scan my code to find if there is somewhere a missing close file that could make this limit reached...
Thank you for your help.
Have a nice day.

I suppose I've found what's wrong, and it was in my codesys application...
I really have a SysFileOpen with no SysFileClose that was called each minutes 😓...
So it takes about 16 hours to reach the limit file count by process which is 1024 (command line ulimit -n to see the limit).
I will run some tests, but I suppose it will be ok now...
Best regards.

Hello, so after 10 days my application didn't crashed, and the codesys runtime is still alive.
So I confirm that the problem was really caused by the openned files limit, due to the missing close I had in my code.
Problem solved ! 😄

Dear Edwin,
Thanks for your answer.
I used Codesys for Raspberry SL.
You're right, the runtime didn't stopped after 2 hours like I supposed and like indacated in the logs:

Hi,
I suppose I've found what's wrong, and it was in my codesys application...
I really have a SysFileOpen with no SysFileClose that was called each minutes 😓...

yes, this could really cause such problems - thanks for the feedback - should help other users
in such situations too!
