Chuck Rolke resolved DISPATCH-1309.
-----------------------------------
Resolution: Fixed
Commits 57c3603 and c27d73b put the router back on track.
* When the console disconnects it usually emits a query immediately (200 uS)
before detaching the links and closing the connection. This ensured that there
was a work item in the router to be processed as the link/session/connection
closed and created the opportunity to perform work on a closed link. Commit
57c3603 fixed that.
* Commit c27d7eb fixed an issue where code on one thread freed an object in
use by another thread. The result was random memory corruption that manifested
itself in a variety of ways.

> Key: DISPATCH-1309
> URL: https://issues.apache.org/jira/browse/DISPATCH-1309
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 1.6.0
> Environment: System 'unused':(
> Fedora 5.0.3-200.fc29.x86_64,
> Python 2.7.15,
> Proton master @ eab1f.
> System 'taj':(
> Fedora 4.18.16-200.fc28.x86_64,
> Python 3.6.6,
> Proton master @ 68b38
> Reporter: Chuck Rolke
> Priority: Major

>
> qpid-dispatch master @ 51244, which is very close to the 1.6 release, has
> various crashes.
> The test network is 12 routers spread over two systems. (Configuration
> generator to be attached.) Four interior routers are in linear arrangement
> with A and C on one system ('unused'), and B and D on the other system
> ('taj'). Each system then attaches four edge routers, one to each interior
> router.
> Running lightweight tests, like proton cpp simple_send and simple_recv to
> ports on INTA and INTB interior routers leads to a crash on INTC. The crashes
> typically look like reuse of structures after they have been freed (addresses
> are 0x9999999999999999). Other crashes hint of general memory corruption
> (crashes in malloc.c).
