OutofMemoryException Mac OS
Introduction
SELECT objectname, cntrvalue FROM sys.dmosperformancecounters WHERE countername = 'Total Server Memory (KB)'; You could save that as a query shortcut in Tools Options Environment Keyboard Query Shortcuts, and get accurate results in a query window much faster than getting inaccurate results from Task Manager. Hello - When doing imports the past 3 days, we have been getting a new and odd set of Exceptions (see below). We take the exception file and re-import those that didn't get imported. OutOfMemoryError usually means that you’re doing something wrong, either holding onto objects too long, or trying to process too much data at a time. Sometimes, it indicates a problem that’s out of your control, such as a third-party library that caches strings, or an application server that doesn’t clean up after deploys.

A few weeks ago I was searching for superb headphones, because I spend most of the day listening to music, while I do concepts/research/coding for my clients. For me it is a way to blend out the surroundings and focus better on the task at hand. After reading a few tests I decided to buy these headphones on amazon.com. The Bose QuietComfort 35 works great with the iPhone 7, but when connecting it to the Macbook you get sometime stuttering and it is unbearable.
The Problem
Searching the net I have found out, that this is a problem created by not providing enough power and/or bandwidth to the bluetooth audio agent on the Mac. This is not a problem of the headphones, but the choppy audio with bluetooth headphones comes from the Mac OS bluetooth audio agent.
The Solution
The solution is quite easy to accomplish: You just need your good old terminal. So enter the following commands in your terminal and after that restart the BluetoothAudioAgent.
Kill the bluetoothAudioAgent with the following command:
If this still does not help you can increase the values and again restart the agent.
I used the higher (second) values and must say, that everything is working like a charm with the Bose QC 35.

Taking the next glorious step down the shining path of our .NET Exception Handling series, today we’ll be looking over the amazing System.OutOfMemoryException. As the name implies, the System.OutOfMemoryException typically occurs when the common language runtime (CLR) is unable to allocate enough memory that would be necessary to perform the current operation.
We’ll spend this article seeing exactly where the System.OutOfMemoryException resides within the .NET exception hierarchy, while also examining a trio of possible causes that could present a System.OutOfMemoryException in your own code. Let the adventure begin!
The Technical Rundown
- All .NET exceptions are derived classes of the
System.Exceptionbase class, or derived from another inherited class therein. System.SystemExceptionis inherited from theSystem.Exceptionclass.System.OutOfMemoryExceptionis inherited from theSystem.SystemExceptionclass.
When Should You Use It?
In spite of the name, the most likely cause of a System.OutOfMemoryException is not technically due to a lack of memory. Instead, a System.OutOfMemoryException can occur when attempting to increase the length of an instance of the StringBuilder class, beyond what is specified by its current MaxCapacity property.
To illustrate, here we have some simple code that generates a new StringBuilder instance called builder:
As indicated by the comments, we’re using a particular override of StringBuilder, in this case the StringBuilder(Int32, Int32) override, which defines the capacity and MaxCapacity property during initialization. In this case, both are set to 3, the length of our firstName string.
We then .Append that initial value to our builder, after which we attempt to .Insert our second value at the end of the existing string index. However, because we’ve already set the MaxCapacity value to 3, and we’ve appended 3 characters, we’ve used up all allocated memory for our StringBuilder instance. Thus, our .Insert attempt throws a System.OutOfMemoryException:
In this case, the issue is that we’ve told the CLR how much memory to allocate using the MaxCapacity property, which was assigned by using the StringBUilder(Int32, Int32) override. The simplest solution is to use a different override, one that doesn’t assign the MaxCapacity property. This will cause the default value to be set, which is Int32.MaxValue (i.e. roughly 2.15 billion).
Another potential cause of a System.OutOfMemoryException is, of course, actually running out of memory during execution. This could be due to repeatedly concatenating large strings, executing as a 32-bit process (which can only allocate a maximum of 2GB of memory), or attempting to retain massive data sets in memory during execution. We’ll use the latter issue in our example snippet below:
This code serves no real functional purpose, but instead just illustrates one possible way of manipulating a huge data set within memory, without using any form of chunking to reduce the allocated memory footprint of the application. In this case, we’re just looping some 200 million times and adding a random number to our list of Doubles every time. Every 10 million loops we also output our current total.
The result is that, eventually, the system cannot handle the amount of memory being used, so a System.OutOfMemoryException is thrown:

The final snippet we’ll look at today is taken from the official documentation. However, this code isn’t producing a System.OutOfMemoryException due to a memory issue, as with our other examples. Instead, this snippet illustrates how System.OutOfMemoryExceptions should be properly handled:

Since a System.OutOfMemoryException indicates a catastrophic error within the system, it’s recommended that anywhere a potential System.OutOfMemoryException could occur be passed to the Environment.FailFast method, which terminates the process and writes a message to the Windows Log. Sure enough, executing the snippet above generates a log entry in the Windows Log, which we can see using the Event Viewer application:
