I've implemented a filter (javax.servlet.Filter). I now have some strange behavior when enabling JMX. As soon as I enable it I will get a "java.lang.OutOfMemoryError: PermGen space" error within short time. I really can't understand why this is. When leaving JMX disabled the application seem to be running fine. ...

Documentation for java.lang.Error says: An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch But as java.lang.Error is subclass of java.lang.Throwable I can catch this type of throwable.

It's these rare ...

In particular, I would like to do something very similar to the following pseudo-code: UIImage* image; try { image = [UIImage imageNamed:@"high_quality_image.png"]; } catch (OutOfMemoryException e) { ...
I have a web site that is throwing OutOfMemoryExceptions on whenever it gets to the following spot in my code: XmlSerializer xs = new XmlSerializer(t, xoverrides); Seeing how this only happens when it is on the web server, i don't have a ton of information on why this is happening. I know that the objects that it is serializing aren't...

The following is throwing an OutOfMemoryException, for XML snippits that are very short and simple (e.g., <ABC def='123'/>): public static T DeserializeXmlNode<T>(XmlNode node) { try { return (T)new XmlSerializer(typeof(T)) .Deserialize(new XmlNodeReader(node)); } catch (Ex...
I am writing a Midlet(using Netbeans) which reads a file containing exactly 2400 lines (each line being 32 characters long) and (extract a part of each line) puts them in an array. I am doing the same for 11 such files( all files have exactly 2400 lines).The Midlet runs fine for reading 6 files and putting them in 6 arrays. However, the ...
I'm getting Out of Memory exceptions surrounding code I've written (about half the time the exception comes from my .dll and half the time it comes from the code just before my .dll; both places deal with bitmap images) when we put it on the live site, but not when we run it through Visual Studio or on our test server. I've been told tha...

I was using this extension method to transform very large xml files with an xslt. Unfortunately, I get an OutOfMemoryException on the source.ToString() line.

I have a timer within my Windows service which is built using C# 2.0. We are in the process of designing the Exception handling. Since it is Timer runs on its own thread we would like to handle the out of memory exception. When that occurs we would like to stop the service. How can we gently stop the service when that happens on the diff...
We have a fairly simple program that's used for creating backups. I'm attempting to parallelize it but am getting an OutOfMemoryException within an AggregateException.
