I had a trial version of the voice notification module installed and it was working. Trial expired and then we were getting a faulted status on the module when we tried to reset it. We updated our license to include that module but when I tried uninstalling and reinstalling, we are getting the same fault:
java.lang.Exception: Exception while starting up module "com.inductiveautomation.phone-notification".
Caused by: java.lang.UnsatisfiedLinkError: Native Library /usr/local/bin/ignition/temp/libcerevoice_eng.so already loaded in another classloader
Also getting the same on the voice module we are using (katherine-english)
