Subject Re: Ignite 1.6.0 suspected memory leak from DynamicCacheDescriptor
Date Thu, 15 Dec 2016 02:54:22 GMT
What do you mean by "embedded instances"? if it's org.apache.ignite.Ignite
object then we have two, one for each .war application deployed.

And what do you mean by "not properly stopped and / or disconnected"? The
application call org.apache.ignite.Ignite.close() only when Tomcat shutdown.
What if there are intermittent network failures?

There are 2 GridKernalContextImpl found in the heap:

    Class Name                                      |   Objects | Shallow
Heap | Retained Heap
   
-------------------------------------------------------------------------------------------
    .*GridKernalContextImpl.*                       |           |             
|              
    org.apache.ignite.internal.GridKernalContextImpl|         1 |         
248 |  >= 1,596,360
    org.apache.ignite.internal.GridKernalContextImpl|         1 |         
248 |  >= 1,599,712
    Total: 2 entries (23,992 filtered)              |         2 |
