[smila-dev] lucene m-threads problems
|
Hi,
I tested ActiveMQ queue overflow and found that there are problems with
lucene.
I collected 50.000 records in queue without processing, after that
starts to process them playing with Listener workers.quantity. As a result:
Lucene index service does not support correctly multi-thread access.
Typical errors:
1. unable to get lock
org.apache.lucene.store.LockObtainFailedException: Lock obtain timed
out: SimpleFSLock@C:\a a\workspace\.metadata\.plugins\
lucene\test_index\write.lock
at org.apache.lucene.store.Lock.obtain(Lock.java:85)

P.S. and Binary storage becomes very-very slow
