The problem happens in cloud server and can be resolved by configuring correct Lucene LockFactory for NFS environment. In NFS, we should set lock type to "simple": ${solr.lock.type:simple} in solrconfig.xml.

See more details in https://lucene.apache.org/core/3_0_3/api/core/org/apache/lucene/store/NativeFSLockFactory.html.
