I'm afraid using MEMP_MEM_MALLOC from interrupt does currently not work: it will allocate any memory from the heap, which is protected via getting a semaphore. Depending on your port, this might work for a while and only crash if the heap is actually protected (used) from non-interrupt context and the interrupt handler tries to access it (as 2nd context). This *might* explain why it works for a while. Being like that, you can still use MEMP_MEM_MALLOC when changing your ISR to a task-based DSR (like Richard explained), if that's a solution for you...
