Hi there,
We are running solr and allocating 1GB to it and we keep having
OutOfMemoryErrors. We get messages like this:
Error during auto-warming of
key:org.apache.solr.search.queryresult...@c785194d:java.lang.OutOfMemoryError:

And like this:
Error during auto-warming of
key:org.apache.solr.search.queryresult...@33cf792:java.lang.OutOfMemoryError:
Java heap space
We've searched and one suggestion was to reduce the size of the
various caches that do sorting in solrconfig.xml
(http://osdir.com/ml/solr-user.lucene.apache.org/2009-05/msg01043.html).
Does this solution generally work? Can anyone think of any other
cause for this problem?
