Ted Ross created DISPATCH-491:
---------------------------------
Summary: Frequent skipped HELLO message from route engine
Key: DISPATCH-491
URL: https://issues.apache.org/jira/browse/DISPATCH-491
Project: Qpid Dispatch
Issue Type: Bug
Components: Routing Engine
Affects Versions: 0.6.1
Reporter: Ted Ross
Assignee: Ted Ross
Fix For: 0.7.0
HELLO messages are exchanged between neighbour routers in a network at an
interval of one-second. Occasionally, an interval will be skipped and there
will be two seconds between HELLO messages sent from a router.
This is caused by measuring the time-since-last-hello to determine if a new
HELLO should be sent. If, for some reason, the invocation of the "tick" method
in the router engine happens just slightly less than one second after the last
tick, the HELLO won't be sent until the next tick.
This can be seen by enabling trace+ for ROUTER_HELLO logs.
