I would like to ask about the error that occurs when I run a program in 4DIAC using OPC UA. When running the program, in the middle of the way an error like the attached picture, how to resolve the error? i use Raspberry Pi to run that program.

hi, may I ask you for a snapshot of your 4diac application that leads to this error?

Hi,

which version of forte and open62541 are you using? If not, I'd try moving to the last version of them.

We just pushed a fix to 1.9.x and develop regarding memory allocation. The bug was when the connection was closed, but maybe it was the root of your problem.

Hi,

I'd suggest to move to the develop branch in forte and the 0.3 in open62541 and compile forte with these versions. The memory problem in Forte is not regarding where it runs, but something is allocated or deallocated wrongly. With the latest versions this problem might have been solved.
