Ken Giusti commented on DISPATCH-2006:
--------------------------------------
Will experiment on possible fixes. Setting release target to 2.0 under the
current assumption this may require breaking changes.
> Set stricter default maxSessionFrames to avoid router OOM under load

> Key: DISPATCH-2006
> URL: https://issues.apache.org/jira/browse/DISPATCH-2006
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Router Node
> Affects Versions: 1.15.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Major
> Fix For: 2.0.0
>
>
> By default, sessions created by the router have an essentially unlimited
> session window size. This can result in unconstrained growth of router heap
> memory during periods of high traffic congestion.
>
> The router needs to use reasonable session incoming window limits by default.
> It's likely that different type of connections - endpoints, inter-router,
> etc - should have different default window sizes. For example it's
> reasonable to provide a bigger window for inter-router links than simple
> endpoint connections.
