----------------------------------
Summary: Proton in endless yielding loop
Key: PROTON-2573
URL: https://issues.apache.org/jira/browse/PROTON-2573
Project: Qpid Proton
Issue Type: Bug
Affects Versions: proton-c-0.37.0
Environment: centos 7
Reporter: AndyGibson
I'm using the python wrapper and have seen this behaviour a number of times but
don't know what precipitates it.
Symptoms are 100% cpu usage and a tcp connection status to 2 (send and receive)
C qpid brokers in "close_wait".
It had, on startup, successfully connected to the broker but sometime later
lost the connection. Scheduled tasks (_timers in _reactor.py) are not running
(presumably starved by a tight loop in the process code)
On turning on debug logging it repeats (endlessly)
*[DEBUG] <proton._reactor.Container object at 0x7fc91cf93310> Yielding*
(presumably from line 251 of _reactor.py)
