Where Is Your Focus for Memory Leak Detection?

Some of these problems are extremely difficult to troubleshoot

*&%#* The system is running slow again!  Now what? Is there a space hog application sucking up all my resources?  Did we just crash? No, must not say that word...must not say that word...  ...still running, just sloooowly.  I wonder if anything new has been installed… Nice if they told me. I overheard that something new might have been installed  last week.  Could there be a memory leak?  Are they checking for one?  Are they looking in the right place? Hide and seek with a leak is NO fun.  How many times have you sat staring at your monitor until your eyes burn and blur, trying to figure out where the problem lies?

Detecting memory leaks

There are so many places to look for a leak, that it is virtually impossible to find manually. And how do I tell the difference between a leak and increased demand?  The symptoms can be  similar. It is important to analyze all of the leak possibilities, because at the end of the day, if you are leaking memory in the JVM, you will find an increase in the heap and an increase in GC activity, culminating in hangs or blocks and finally, OutOfMemory exceptions.  If the Java code is meant to run on a server 24 hours a day, then memory leaks can become significant.  Even the smallest leak in code that is run continuously will eventually result in the JVM exhausting all of the memory available.

Some examples of Memory Leak causes are:

  • Handle Leak
  • Class Loader Leak
  • Thread Leak
  • Unchecked arrays
  • Bugs in the code
  • Unchecked hash map growth
  • Programmers forgetting to close prepared statements, sockets or file handles

Some of these problems are extremely difficult to troubleshoot.  These leaks need to be found, addressed and handled ASAP. With the number of things an IT group has to handle on any given day, there just isn't the time or the manpower to take an exceptional amount of time to deal with manual leak detection.  Automation is the only logical way to find them.  To be notified when there is a possible leak detected and how to mitigate a JVM failure is the optimal solution.  No headaches, no blurry vision, no screaming users.  How good life could be. For more information on how you can automate your leak detection and ease the stress of your day, listen to the Nastel TechTalk, “Java Memory Leaks II – Detection to Diagnostics

The Internet of Things will challenge the status quo of how IT and development organizations operate. Or will it?

Digitization is driving a fundamental change in society that is transforming the way businesses work with their customers, their supply chains and their people.

The Transparent Cloud-computing Consortium (abbreviation: T-Cloud Consortium) will conduct research activities into changes in the computing model as a result of collaboration between "device" and "cloud" and the creation of new value and markets through organic data processing High speed and high quality networks, and dramatic improvements in computer processing capabilities, have greatly changed the nature of applications and made the storing and processing of data on the network commonplace.
Your business relies on your applications and your employees to stay in business. Whether you develop apps or manage business critical apps that help fuel your business, what happens when users experience sluggish performance? You and all technical teams across the organization – application, network, operations, among others, as well as, those outside the organization, like ISPs and third-party providers – are called in to solve the problem.
Digital transformation is too big and important for our future success to not understand the rules that apply to it. The first three rules for winning in this age of hyper-digital transformation are: Advantages in speed, analytics and operational tempos must be captured by implementing an optimized information logistics system (OILS) Real-time operational tempos (IT, people and business processes) must be achieved Businesses that can "analyze data and act and with speed" will dominate those t...

I'm a lonely sensor. I spend all day telling the world how I'm feeling, but none of the other sensors seem to care. I want to be connected. I want to build relationships with other sensors to be more useful for my human. I want my human to understand that when my friends next door are too hot for a while, I'll soon be flaming. And when all my friends go outside without me, I may be left behind. Don't just log my data; use the relationship graph. In his session at @ThingsExpo, Ryan Boyd, Engi...
