Dear Team, I'm facing an issue that tomcat from task manager is consuming around 60 GB of memory while from Oracle Java Mission Control is showing maximum 10 GB (Attached screenshots), and from time to time the server hang due to insufficent memory. can you please advise why the above is showing like that? and why the memory of the server is not reducing? Tomcat Version: 8.0.30 JDK: 1.7.0_67 I couldn't find the screenshot. Anyway​, the issue you mentioned is very interesting. Usually I saw some difference(in MB) between task manager data and JMC data...but not like this. Can you please let us know about the Java Heap, Permgen and thread stack size configuration? For starter, I will suggest to take a heap dump and look into it. It will show you which objects are live and holding the memory. Also it will be awesome if you can enable Native Memory Tracking for your TC instance. Thanks! Suvendu
