Description
Background:
Integrating FMU from OM in a real-time simulation for Hardware in the Loop test using dSPACE HW & SW. After 3 hours of test the simulation is stopped due to NULL-Pointer exception.
dSPACE support report that exception caused by pool_malloc. I try to defined the OMC_NO_THREADS when compiling the rt-app in case the pthread was the problem to no avail.
I check the FMU with FMUChecker for -s 11000 -h 1e-3 and it doesn't seem to have any problem.
Questions:
Since the problem is reproducible and alway happend after around 10700s - 11000s (~3h)simulation time, could it be a memory leak issue?
Any idea on how to debugg it further? or the underlying problem is another thing?
