Segmentation fault after reconnection to processes

I have a layout with 5 rt-processes . After stopping all the processes and restarting them again reconnecting all processes result in a Segmentation fault:

Thread 1 "testmanager-ng" received signal SIGSEGV, Segmentation fault. 0x00007ffff75c9c68 in ?? () from /lib64/libpdcom5.so.2
