Alberto Gomez updated GEODE-8278:
---------------------------------
Summary: Gateway sender queues using heap memory way above configured value
after server restart (was: Gateway sender queues using up a lot of heap space
after server restart)
> Gateway sender queues using heap memory way above configured value after
> server restart
> ---------------------------------------------------------------------------------------

> Key: GEODE-8278
> URL: https://issues.apache.org/jira/browse/GEODE-8278
> Project: Geode
> Issue Type: Bug
> Components: eviction
> Reporter: Alberto Gomez
> Assignee: Alberto Gomez
> Priority: Major
>
> In a Geode system with the following characteristics:
> * WAN replication
> * partition redundant regions
> * overflow configured for the gateway senders queues by means of persistence
> and maximum queue memory set.
> * gateway receivers stopped in one site (B)
> * Operations sent to the site that does not have the gateway receivers
> stopped (A)
> When operations are sent to site A, the gateway sender queues start to grow
> as expected and the heap memory consumed by the queues does not grow
> indefinitely given that there is overflow to disk when the limit is reached.
> But, if a server is restarted, the restarted server will show a much higher
> heap memory used than the memory used by this server before it was restarted
> or by the other servers.
> This can even provoke that the server cannot be restarted if the heap memory
> it requires is above the limit configured.
> According to the memory analyzer the entries taking up the memory are
> subclasses of VMThinDiskLRURegionEntryHeap.
> The number of instances of this type are the same in the restarted server
> than in the not restarted servers but on the restarted server they take much
> more memory. The reason seems to be that they hold references to
> previousEvictionNode and nextEvictionNode.
