could not get chConfig cache reference: read configuration for channel peers failed
2018/07/17 13:23:13 create channel client fail: event service creation failed: could not get chConfig cache reference: read configuration for channel peers failed
配置文件中没有指定组织的certificateAuthorities
如果配置文件中缺少50,51行：
44 organizations:
45 org1:
46 mspid: peers.member1.example.com
47 cryptoPath: ./crypto-config/peerOrganizations/member1.example.com/users/[email protected]/msp/
48 peers:
49 - peer0.member1.example.com
50 certificateAuthorities:
51 - ca.org1.example.com
会导致：
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x44351d3]

需要在config.yaml中配置certificateAuthorities：
65 certificateAuthorities:
66 ca.member1.example.com:
67 url: https://ca.member1.example.com:7054
68 tlsCACerts:
