What is leaking int arrays in my program?
I have Java program that, over about 16 hours, is slowly filling the heap with integer arrays that the GC is not getting rid of. I only have VisualVM available to diagnose the problem, which is how I found that it’s int[] that is filling the heap. Any ideas how I can find the source of the int[] creation? I’m
Odd heap usage pattern
I have a repeating process that: gets some data from the database builds some objects in memory, adding to a Collection writes the data from the Collection to a file All of the objects/Collections go out of scope or are set to null after each iteration. (The Collection is reused for each iteration.) Using Java VisualVM, I see a graph
Why is tomcat using more and more heap space during idling?
I start tomcat using startup.bat and do nothing more with it. It is a plain vanilla installation (Version 7.0.47), as far as I know. When connecting with a JMX tool, like VisualVM I see the usage of Heap space constantly increasing. Until some garbage collection happens. And then it starts all over, again. Why is that so? What is tomcat

Java VisualVM does not show/list my tomcat java process

Tomcat is running with -Xmx7196m, where as jvisualvm is running with -Xms24m and -Xmx256m. Could this be the cause? Answer You need to add the JMX parameters to enable the JMX connection to your
Viewing MBeans through jstatd
I am trying to monitor all Java processes running on a server via jstatd. I’ve got it set up enough that I can connect with VisualVM and see all running processes. Most displays work fine, however certain things (especially CPU usage and MBeans) do not display. Instead, it says: MBeans Browser Data not available because JMX connection to the JMX
VisualVM Not showing ANY methods called for CPU Performance Profiling
I’m running a Java 1.6_21 SDK build app. Its been build in Eclipse, and i’m using the VistualVM eclipse plugin to launch VisualVM when the app starts. When I go to the Profile tab and click CPU profiling, It only shows the THREADS that are running, but it doesn’t show any METHOD calls. Quite litterally, none. I’ve googled a whole
OutOfMemory Exception – how does VisualVM help locate the memory leak with heapdump file?
I’ve been testing my webapp locally on my pc and monitoring it with VisualVM. I recently also started using JMeter, as it was suggested that I should do some load testing since I suspected that I have a slow memory leak somewhere. Today my webapp finally threw the OutOfMemory exception. I had the HeapDumpOnOutOfMemoryError and HeapDumpPath params set in case
