Vishal Sharda created DISPATCH-470:
--------------------------------------
Summary: Router terminated by itself while sitting idle
Key: DISPATCH-470
URL: https://issues.apache.org/jira/browse/DISPATCH-470
Project: Qpid Dispatch
Issue Type: Bug
Components: Routing Engine
Affects Versions: 0.6.1
Environment: Debian 8.3, Apache Qpid Proton 0.13.0 for drivers and
dependencies, Hardware: 8 CPUs, 61 GB RAM, 30 GB HDD each on 5 separate machines
Reporter: Vishal Sharda
We are running a network of 5 inter-connected routers each on a separate host.
One of the routers in this network terminated after running successfully for 7+
days. The router was idle (not receiving/sending any messages) when this
happened. After analyzing the core dump, it turned out to be something related
to mutex lock in multithreading.
Here is the full bt:
Reading symbols from qpid-dispatch/qdrouterd...(no debugging symbols
found)...done.
