Sanne Grinovero commented on ISPN-939:
--------------------------------------

it's a wiki you should be able to write there ;)
I have to admit it's not there because I didn't know. Also I think my suggestion above should work, but please confirm it before we make it a recommendation.
Also, this is a workaround, I'll have to figure out how to prevent it from happening at all! Usually workarounds are better described in the JIRA, so people having the same issue in the short time will find it, hopefully for the long time the issue should be solved.

> Using a scenario similar to the one described in ISPN-909:
> 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).
