CODESYS Control RTE: C0297: Stack overflow detected

[AlfredoQuintero]

Hello:
I am experiencing the following error:
[ERROR] C0297: Stack overflow detected in DecodeOID. Maximal Stack Size: 64512. Calculated Stack Size: 68024. Call Hierarchie:
I cannot find a clear explanation on where to increase the stack for the Control RTE soft-PLC.
If you know where to tweak, will be grateful if you let me know.

Google found this don't know if it will help

Hello Parky: I have found these but were not so helpful, unfortunately.

I tried building the same program in Codesys for Windowos, and it is possible to build and load without the stack overflow problem.

If the SNMP service library the stack overflow problem manifests.

Check for a function with a Divide by Zero ?

 

[drbitboy]

Is this when compiling or running?

If running, then check the logic to see whether a routine might be calling itself, either directly or indirectly.

Stack overflow is often the result of unconstrained recursion.

I am no codesys expert, but just reading through "The book of codesys" there are a bunch of provided POU's to do implicit checks on your program, might try using one or even all of these.

Quite a few available in there, and perhaps it'll help you figure it out.

Application>Add Object>POU for implicit checks

maybe it works, maybe not, worth a shot

Thanks for your comments. As I explained in post # 5, I fiex the problem by not updating the SNMP library.
