I'm writing received date on the memory(RAM) and after a while (unknown and depends on received data), write a block of received data (unknown size and dep...
This image shows fragmentation in my app's address space. Is there any way to force the (third-party) dll images (purple) together to eliminate (or mitigate) the fragmentation? This app will run on 32-bit XP; obviously when we eventually move to 64-bit Windows 7, this problem will go away. Thanks! ...
I have a file from which I read data. All the text from this file is stored in a String variable (a very big variable). Then in another part of my app I want to walk through this string and extract useful information, step-by-step (parsing the string). In the meanwhile my memory gets full and an OutOfMemory exception keeps me from furth...
Hi, I'm new to Java and really need your help. I am presently using a queue, a receiver thread puts data into this queue and the parser reads out of this. But the problem is the receiver may receive at incredible peak speed, eg. 3000/sec, while the parser only parses at 100/sec. EDIT:I have checked, the queue first stays at 100 o...
I use SQLite in a java program. While the java program runs, several queries are sent to the database as well as temporary tables are created in memory and then deleted (using DROP). The problem is that while the number of various operations in the database increases, the memory usage from the java program also increases. As a result, ...

Hi, I am trying to reproduce java.lang.OutOfMemoryException in Jboss4, which one of our client got, presumably by running the J2EE applications over days/weeks. I am trying to find a way for the webapp to spitout java.lang.OutOfMemoryException in a matter of minutes (instead of days/weeks). One thing come into mind is to write a selen...
This code works great for generating thumbnails, but when given a very large (100MB+) TIFF file, it throws OutOfMemoryExceptions. When I do it manually in Paint.NET on the same machine, it works fine. How can I improve this code to stop throwing on very large files? In this case I'm loading a 721MB TIF on a machine with 8GB RAM. The Ta...
Can the new operator throw an exception in real life? And if so, do I have any options for handling such an exception apart from killing my application? Update: Do any real-world, new-heavy applications check for failure and recover when there is no memory? See also: How often do you check for an exception in a C++ new instructio...

Hi all, I am trying to figure out why Jetty 6.1.22 is running out of memory on my laptop. I have 2 web applications running JBoss Seam, Hibernate (with EHCache), and separate Quartz scheduler instances. With little load, the server dies throwing OutOfMemory. What can I look for? Would you think that I am not properly closing handles...

Thus all images are needs at most 5 MB in memory, even with additional information about size, format etc. But after 400th image Image.FromFile() throws OutOfMemory exception. So, what's the problem? ...
