    Please review:
    http://wiki.apache.org/solr/UsingMailingLists

    You've given us no information to go on here, what are you
    trying to do when this happens? What have you tried? What
    is the query you're running when this happens? How much
    memory are you allocating to the JVM?

    You're apparently sorting, how many unique values are there
    in the fields you're sorting? How are the fields you're sorting on
    being analyzed?

    Best

    Hi Erick,

    In continuation to my below mails, I have a socket based multithreaded
    server that serves in average 1 request per second.
    The index size is 31GB and document count is about 22 millions.
    The index directories are first divided in 4 directories and then each
    subdivided to 21 directories.
    I share a ParallelMultiSearcher instance for all the searches without
    closing the readers.
    I have given the JVM 5GB of memory.


    Normally server runs smooth but sometimes when there is some complex
    phrase query with other fields executed, it gives below error and
    hangs.
    I think that there is no sorting for the query that creates below
    error, please help.

    Complicated with all those indexes.

    3 suggestions:

    1. Just give it more memory.

    2. Profile it to find out what is actually using the memory.

    3. Cut down the number of indexes. See recent threads on pros and
    cons of multiple indexes vs one larger index.
