Segments locked during merge

    Details

      Description

      We're getting failures on acquiring locks during merges. Here is the configuration:
      Infinispan: 3 caches: lockCache (replicated, volatile, no eviction), metadataCache (replicated, persisted, no eviction), dataCache (distributed, persisted, eviction).
      Node 1: coordinator, IndexWriter open constantly and writing a stream of documents
      Node 2: opens a read-only IndexReader on-demand to perform queries (we're moving to use IndexReader.reopen() ).

      Occasionally when performing queries on node 2 we get the attached stack traces. We then get corrupt indexes (java.io.IOException: Read past EOF).

      We are using the default Distributed Segment Lock Reader, default 16K chunks and no tuning of the merge policies.
