Didn't see this error before sorry, I really need to be more attentive:
Segmentation fault (core dumped)
Caused by trying to write to the same log file from two different instances of mmdvm_bridge.
Change the log file locations in both of your new MMDVM_Bridge.ini and DVSwitch.ini files to point to the new locations
Also make sure that your new DMRIds.dat file locations are correct in your MMDVM_Bridge.ini files or you they won't get updated.
