Reason-

This can happen when you stop CAS forcefully when it is performing some action like running crawl. It messes up CAS’s locking mechanism

Fix –

• Go to cas state

cd <Endeca-Installation>/CAS/workspace/state/cas

• take a backup of db directory

mv db db_bk

• start Cas service

<Endeca-Installation>/CAS/11.3.0/bin/cas-service.sh

Once CAS starts remvoe the db_bk directory
