ArrayList Page Rank, if the user has not chosen a specific order in which to show the page LayoutType for this page. SessionFactoryOptionsImpl 0x6db944498 160 536 - jdbcServices org. Is it exhibiting leak behaviour? I will place that detail here and leave the decision up to you as to whether a defect should be created. TypeLocatorImpl 0x6db9d9fe8 16 16 - typeResolver org. Max, This is, unfortunately, the response I expected. HashMap 0x6db9dffb0 48 400 - cacheAccess org. SessionFactoryImpl 0x6db944410 136 445 322 392 - class org.
I'm not expecting you to change anything in Hibernate, I just want a qualified oppinion on this. Have a question about this project? SessionFactoryServiceRegistryImpl 0x6db9443b0 48 11 032 - properties java. My questions is as follows: 1 Is every operation taking 2-4 M too big in our case? The number of columns will be determined by the length of this list. ConcurrentHashMap 0x6db9dde50 64 88 - observer org. What it sounds like at first glance is that you're keeping a lot of data in memory after it's no longer needed. SessionFactoryObserverChain 0x6db9dde90 16 200 - namedQueryRepository org.
CacheImpl 0x6db9e26e0 40 104 - sqlFunctionRegistry org. Using a simple statement in this case is much faster and using a PreparedStatement with parameters just like in the example above is even faster, given that large amounts of data are processed. The userid of the creating user The userid of the last modifying user The location that this data is conceptually stored in. IdentNode objects and their associated objects consuming memory. We have an application that handles parsing of a file from 1 format to another. I have submitted this bug for two reasons. We suspect that there might be a memory leak in this library.
Anyway, when the native queries were indeed removed and after running for a couple of days the memory has disappeared. We can then manipulate the referenced object delete without having to moddify this object. Properties 0x6db9443e0 48 3 616 - sessionFactoryOptions org. Also, when the same query is translated to hql, the memory consumption problem goes away this is how I have worked around the problem. You'd need to do some serious profiling to find out for sure where to look though.
Thanks, Jarrod I too ran into this problem. String 0x6db9a9cd8 e278da6b-637c-4fbe-b870-6b1868b68398 24 112 - cacheAccessStrategiesMap java. Second, I thought it was important for you to know even if you already knew it before that your policy of using PreparedStatements without parameters is not the best by far. By specifying an id instead of a many-to-one for the object, we can facilitate a weak link between the 2 objects. This suggestion from the attached thread seems to be pertinent: Try adding the new properties hibernate.
The value should be one of the constants defined in this class. He also provided a test case which is attached to the bug report bug 920825 -. And we do not have so many users. The id of the layout template for this page. Iterator The list of internationalized names. This is just a code snippet of the app. After looking at the references in the heap it looks like the query is rooted in the QueryPlanCache.
Did the jira defect ever get entered for this problem? It uses hibernate to access the database and retrieve the parameters for its parsing. HashMap 0x6db9e5928 48 48 - identifierGenerators java. Most likely something like a List of Lists of retrieved data , or you keep sessions open far too long containing Lists of records. I suspect that a more simple native sql query would also cause the same problem, but I have not tested this. For our application we have about 150 different proxy types, and our app can have over 100 threads.

The query listed below that I know causes the leak is very complex. The value should be one of the constants defined in this class. Hi: I am investigating a Spring, Hibernate application performance issue. Basically whenever a user saves a file in our file folder the application will automatically retrieve that file and parse it to the corresponding file format. TypeResolver 0x6db9d9ff8 24 6 280 - queryPlanCache org. First, I'm not very familiar with Hibernate i.
