Chuck Rolke commented on DISPATCH-1309:
---------------------------------------
A console disconnect can crash a stand-alone interior router with no client
traffic. Start a router with:
{{router {}}
{{ debugDumpFile: qddebug-INTB.txt}}
{{ mode: interior}}
{{ id: INTB}}
{{}}}
{{listener {}}
{{ http: true}}
{{ port: 5672}}
{{}}}
{{log {}}
{{ outputFile: INTB.log}}
{{ enable: trace+}}
{{ module: DEFAULT}}
{{}}}
Connect your browser to 127.0.0.1:5672
In the Connect tab repeatedly disconnect and connect.
After some small number of tries my router crashes with one of a wide variety
of core dumps.
Note this this is an issue with release 1.5.0 as well.

> 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

>
> 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).
