2-org-3-peers or 3-org-2-peers marbles，I meet this problem

[wenshuohan]

When I tested the merbles example with caliper, I tried to replace its network configuration with two organizations, each with three peers. Or three organizations, each organization has two peers, but there is such a mistake when starting the network.In my previous tests, two organizations and four nodes could run normally.
the error is:

Hey, my experiance showed that caliper error messages will not help you at all. Have a look at the logs of the docker container and search for errors there. To do so type docker ps -a. If you are lucky there will be docker containers that "exited". Type docker logs org2.example.com or whatever container caused issues.

[wenshuohan]

嘿，我的经验表明，卡尺错误信息根本无法帮助你。查看docker容器的日志并在那里搜索错误。这样做类型docker ps -a。如果幸运的话，会有“退出”的泊坞容器。键入docker logs org2.example.com或任何容器导致问题。

thankyou very much,when i watch the peer0.org1.example.com docker logs,I find there has a wrong:2018-10-29 13:45:58.021 UTC [couchdb] handleRequest -> WARN 004 Retrying couchdb request in 125ms. Attempt:1 Error:Get http://couchdb.peer0.org1.example.com:5984/: dial tcp 172.22.0.2:5984: getsockopt: connection refused.
may be it is the point.

[aklenik]

@wenshuohan running many peer containers with couchDB is really resource demanding. In this case, the connection could be lost between the peer and its DB under high (or even smaller) load.
Try to spread your network among different machines and see if the error persists.

[wenshuohan]

@aklenik Thankyou,I will have a try.

[houqinghui]

have you resolved the problem ? refer to #112
A: One solution:
a. docker-compose -f network/fabric-v11/2-org-2-peer/docker-compose.yaml up -d in another shell
b. remove "start": "docker-compose -f network/fabric-v11/2-org-2-peer/docker-compose.yaml up -d", from config.json
c. node benchmark/simple/main.js
another solution:
Execute commands under root privileges. @wenshuohan

[wenshuohan]

@aklenik have you take a try about stronger machine/VM，could you tell me how can i spread the network among different machines。

[aklenik]

@wenshuohan Any luck with your network? There is no ultimate method for deploying Fabric on multiple machines. Try to take a look at Hyperledger Cello. Or start the Fabric binaries manually on each machine.
But once your network is running, Caliper doesn't care about its location, just set the right endpoint addresses.
