• Details:
  When running docker container with attached volumes, the mumur executable did not appear to write to the log file defined in murmur.ini.
  Logging appears to be restored if modifications to launch parameters are made, taking murmur.x86 out of the foreground as follows:
  Removal of the "-fg" launch parameter contained in MURMUR_OPTS env variable in /usr/local/bin/entrypoint-functions.sh

MURMUR_OPTS="${MURMUR_OPTS} -v -ini ${CONFIGDIR}/murmur.ini"
