B.Nicolotti commented on LUCENE-4467:
-------------------------------------

We left only one web applicatin writing the index with a LockTimeOut of 120s, but we've got
a problem:

Fri Oct 26 10:08:02 CEST 2012:com.siap.WebServices.Utility.UtiIndexerLucene caught an exception:
13341879 java.io.FileNotFoundException
 e.toString():java.io.FileNotFoundException: /usr/local/WS_DynPkg/logs/index/_8c0_2c.del (No
such file or directory),
 e.getMessage():/usr/local/WS_DynPkg/logs/index/_8c0_2c.del (No such file or directory)

indexing:/usr/local/WS_DynPkg/logs//log_2012-10-26.20121026100648672-1.log caught an exception:
1543979 org.apache.lucene.store.LockObtainFailedException
 e.toString():org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: NativeFSLock@/usr/local/WS_DynPkg/logs/index/write.lock,
 e.getMessage():Lock obtain timed out: NativeFSLock@/usr/local/WS_DynPkg/logs/index/write.lock
org.apache.lucene.store.Lock.obtain(Lock.java:84)
org.apache.lucene.index.IndexWriter.<init>(IndexWriter.java:1098)


and the index is no longer useable. The index seems very sensitive, but we've implemented
the indexing only once after writing to logs, and so if the index is broken we've to erase
the index

What do you suggest?

Is it possibile to set an infinite waiting time to get the write.lock?

Many thanks

Best regards
