Overpass API FILE_ERROR Operation not permitted 1

I am following this https://wiki.openstreetmap.org/wiki/Overpass_API/Installation guide to install OSM3S server on Ubuntu using vagrant.

After populating DB whenever i try to Start Dispatcher Deomon using the command:

nohup $EXEC_DIR/bin/dispatcher --osm-base --db-dir=$DB_DIR &

I get the following error:

File_Error Operation not permitted 1/vagrant/test/osm-3s_v0.7.52/db//osm3s_v0.7.52_osm_baseUnix_Socket::4

If i try to rename the osm file in my db directory from osm_base_version to osm3s_v0.7.52_osm_base it gives the following error:

File_Error Address already in use 98/vagrant/test/osm3s_v0.7.52/db//osm3s_v0.7.52_osm_base Unix_Socket::4

I tried to run the command after removing the stale lock files /dev/shm and osm file in db directory (mentioned the Troubleshooting section of installation guide) but it shows no success .
