Fixed In Version:	wallaby-0.16.1-1	Doc Type:	Bug Fix
Doc Text:	Cause: There should be only one Wallaby agent running on the qpid broker, but in some rare cases it may be possible for two Wallaby agents to start on the same broker. Consequence: Running wallaby shell commands could have unpredictable results if more than one Wallaby agent is on the broker. Fix: The wallaby shell now ensures that only one Wallaby agent is running on the specified broker as part of its startup. Result: The aforementioned unpredictable behavior will be avoided.

Description Lubos Trilety 2012-08-23 14:08:21 UTC

Description of problem:
Wallaby console should detect if there are two or more wallaby agents connected to the broker. In such case it should print clear error, something like:
"I'm refusing to run against two or more agents; kill one of these"

Now it prints general error message, which are not true:
"fatal:  cannot find a wallaby agent on the specified broker (host:5672); is one running?"

Version-Release number of selected component (if applicable):
wallaby-utils-0.12.5-10

How reproducible:
100%

Steps to Reproduce:
1. set two wallaby agents so they connect to the same broker
2. try to run some wallaby command, see output
# wallaby -H host list-nodes
Console Connection Established...
fatal:  cannot find a wallaby agent on the specified broker (host:5672); is one running?

# wallaby -H host1 list-nodes
Console Connection Established...
fatal:  there is more than one Wallaby agent running on the specified broker (lt-rhel5_64-old:5672); only one may run at a time
  Agents found:
    pid 10150 on host1
    pid 24612 on host2
    pid 14393 on host3
    pid 23114 on host4
