Today I've been alerted by one of my collegues that our Lucene-based indexing solution no longer refreshes the searchers and thus we never get any new indexed documents.
Since I didn't find anything in the log from log4j I did a "kill -3" on the process and found two very interesting things: Almost all multisearcher threads were in this state: "MultiSearcher thread #1" daemon prio=10 tid=0x0000000001900960 nid=0x81442c waiting for monitor entry [0xfffffd7d269ff000..0xfffffd7d269ffb50] at java.util.Vector.size(Vector.java:270) - waiting to lock <0xfffffd7f0114ea28> (a java.util.Vector) at org.apache.lucene.search.BooleanQuery$BooleanWeight.<init>(BooleanQuery. java:95) at org.apache.lucene.search.BooleanQuery.createWeight(BooleanQuery.java:220 ) at org.apache.lucene.search.BooleanQuery$BooleanWeight.<init>(BooleanQuery. java:97) at org.apache.lucene.search.BooleanQuery.createWeight(BooleanQuery.java:220 ) at org.apache.lucene.search.Query.weight(Query.java:85) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:85) at org.apache.lucene.search.MultiSearcherThread.run(ParallelMultiSearcher.j ava:251) And, additionally I found another stacktrace in the stdout-log which I find interesting: Exception in thread "MultiSearcher thread #1" org.apache.lucene.search.BooleanQuery$TooManyClauses at org.apache.lucene.search.BooleanQuery.add(BooleanQuery.java:79) at org.apache.lucene.search.BooleanQuery.add(BooleanQuery.java:71) at org.apache.lucene.search.PrefixQuery.rewrite(PrefixQuery.java:50) at org.apache.lucene.search.BooleanQuery.rewrite(BooleanQuery.java:243) at org.apache.lucene.search.BooleanQuery.rewrite(BooleanQuery.java:243) at org.apache.lucene.search.IndexSearcher.rewrite(IndexSearcher.java:166) at org.apache.lucene.search.Query.weight(Query.java:84) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:85) at org.apache.lucene.search.MultiSearcherThread.run(ParallelMultiSearcher.j ava:251) Has anyone ever seen these errors and knows why they might occour?
