Pinned topic ISA shows memory leak even though we have enough max heap of 1024 mb

‏2012-08-10T15:42:05Z |
I am using ibm ISA for analysing the GC for 3 JVM's.
Test was run for 2 hours. server2 and 4 has good graph and server 3's used heap after collection is increasing.
Hence the recommendation from ISA is like 'your app may be leaking memory'.

The min and max settings for the 3 JVM are 512 mb and 1024 mb.

questions:

Heap graph starts at 512 mb and it goes only up to 600 mb. Then why ISA is complaing abt memory leak even though we have until
1GB.

    Hi,
    I presume you are using GCMV within ISA to get the information about a memory leak. It is not suggesting that you have run out of memory, just that you're application may be leaking in which case it would eventually run out of memory. It suggests a memory leak because the Used heap is increasing at a faster rate than the workload of the application which indicates a leak.

    Hope this is helpful
