Hello @abhijitnath89axa ,

the error indicates a missing python module UserDict which required by the App SA-VMNetAppUtils

edit the file /opt/splunk/etc/apps/SA-VMNetAppUtils/local/apps.conf and change state = enabled to state = disabled. If there is no such file try /opt/splunk/etc/apps/SA-VMNetAppUtils/default/apps.conf

After that try to start Splunk.

Let me know how it went.

We also had to disable the Vmware app
