Using a scenario similar to the one described in
Infinispan: 3 caches: lockCache (replicated, volatile, no eviction), metadataCache (replicated, persisted, no eviction), dataCache (distributed, persisted, eviction, hash numOwners=2)
Node 1: coordinator, IndexWriter open constantly and writing a stream of documents, committing after each one
Node 2: opens a read-only IndexReader to perform queries, using reopen to keep in sync with the updates coming from node 1
If we "kill -9" node 2 (to simulate a crash), we get a SuspectException in node 1 during the pre-commit phase (within IndexWriter.commit()). Catching the Throwable we then close() the writer but from then on we get "Read past EOF" errors when trying to access the index (both with readers and writers).
