How do i configure maxClientCnxns in zoo.cfg for storm?

Today we found that some of the workers on our machines were not getting initialised properly. We debugged the issue and found that it was because of the default value of maxClientCnxns in zookeeper. The default value is 10. This means that there cannot be more than 10 connections from a single client machine to a single member of zookeeper ensemble. By increasing this parameter the issue got resolved. I would like to know how to decide upon the value which has to be assigned for this parameter.
Assume that I have a storm cluster containing m machines each having n supervisor ports. I am running nimbus, supervisor and ui on one of these m machines. For safer side should I assign the value to be n+3(considering nimbus, supervisor and ui on the master machine)?
