[jira] [Created] (QPID-3211) Drop VPN between broker & client
causes stack trace in tight loop in driver.
Drop VPN between broker & client causes stack trace in tight loop in driver.
----------------------------------------------------------------------------
Key: QPID-3211
URL: https://issues.apache.org/jira/browse/QPID-3211
Project: Qpid
Issue Type: Bug
Components: Python Client
Affects Versions: 0.8
Environment: machine = F14 (vm)
installed:
qpid-cpp-server-store-0.8-4.fc14.x86_64
qpid-cpp-client-0.8-4.fc14.x86_64
qpid-cpp-server-ssl-0.8-4.fc14.x86_64
qpid-cpp-client-ssl-0.8-4.fc14.x86_64
python-qpid-0.8-3.fc14.noarch
qpid-cpp-server-0.8-4.fc14.x86_64
Reporter: Jeff Ortel
When dropping the VPN between the broker (machine) and client (machine) causes the python-qpid driver to enter a tight loop raising exceptions. The following trace is written to the log endlessly and process takes 100% CPU. The python driver seems to be in a broken state. It's possible that this condition can occur when other significant networking issues arise but not sure.
