Java TransportClient Memory Leak

Elastic Stack Elasticsearch
1

I've had an ongoing problem using the Java TransportClient injected through
elasticsearch-spring. When trying to load test my client once I hit the
180k request mark requests start to hang, some take 20+ seconds. I've load
tested the elasticsearch directly to make sure it wasn't a configuration
problem over there. When I kill my load test if I start it up again it
picks up just as slow until I restart my client. After checking the GC logs
fingers point to memory being used up.
This is how I am doing my search:

    String escapedQuery = LUCENE_PATTERN.matcher(params.getQuery()).

replaceAll(REPLACEMENT_STRING);

    SearchRequestBuilder theSearch = esClient.prepareSearch(THE_INDEX)
            .setSearchType(SearchType.QUERY_THEN_FETCH);


    theSearch.addFields(params.getAsStringArray(params.getReturnFields

()));

    QueryBuilder theQuery = QueryBuilders.queryString(escapedQuery)
            .field(TICKER_FIELD)
            .field(NAME_FIELD)
            .analyzer(WHITESPACE_ANALYZER)
            .useDisMax(true)
            .defaultOperator(QueryStringQueryBuilder.Operator.AND);


    theSearch.setQuery(theQuery)
            .setSize(params.getSize())
            .setFrom(params.getFrom());


    SearchResponse resp = theSearch.execute().actionGet();

Are you restarting your webapp (modify code live) instead of restarting Tomcat?

If so, it's due to a very old issue in Google guice as far as I remember. Some threads are not deleted and still here in the JVM when restarting the webapp.

I think that's not the issue. When I restart the tomcat everything works as
expected again until I get to the 180k request mark at which point it
cannot handle anymore requests until the app is restarted again. The app
conks out at 180k almost on the mark every time regardless of stress
testing with 1 thread or 100 threads and always preforms the the same after
the webapp is restarted.

Figured out the issue, turns out not to be elasticsearch. The default
tomcat session is set to 30 minutes which was taking up all the memory.
After fixing that issue the elasticsearch load test performed perfect.
