OCSP for multirootCA is not working

I am not sure if I am configuring the CFSSL in the right way. Please let me know if there is an issue with my configuration.

Following is the scenario that I have tried to setup:

Db used : postgres
1 Root CA and 5 Intermediate CAs signed by that rootCA { ICA1, ICA2, ICA3, ICA4 and ICA5 }

Used ICA1 in the **cfssl serve** command.
Used others ICAs in **multirootca** command (creating a configuration)

I am able to issue certs with all the ICAs just fine. I have the entries for the certs in the certificate table also.

Running **ocsprefresh** command fails with the following exception :
`bin/cfssl ocsprefresh -db-config db-config.json -ca ICA2.pem -responder OCSP/ocsp.pem -responder-key OCSP/ocsp-key.pem
