My Application is a tomcat application and which talk to rabbit MQ . heap is reaching 3 GB and after a major GC it come down to around 700 megabytes .|
But the issue is, the application was Ideal for more than 12 Hrs , So there will be no growth of objects . But Objects are getting created and collected by GCs .
Is that a Usual behavior , Because After starting the application , it consumes max 1 GB of Heap , But when I have stated the test with 100 concurrent users , the as usual the heap growth happen , and all fall happen after the GC collected ( 3 GB max heap) . But After stopping the test , the heap is not coming to normal .
I have taken Dump after a Major GC and Dump when it reach almost 3GB . Found that the unreachable object char array is the top contributor .
But where is the issue in char array , I'm unable to find it .
I have attached the screenshot of heap usage in ideal state , after I stop a test .
Please guide me how to check the issues from the MAT on the heap dump .
