! start dispatcher failed, see dispatcher.log for error: fork/exec /Users/hamidfzm/Go/src/github.com/xiaonanln/goworld/components/dispatcher/dispatcher: resource temporarily unavailable

I'm trying to start demo chat server but I get error from dispatcher start and the dispatcher.log is empty. What is the problem here?

[xiaonanln]

This could be due to some resource limit. I have never seen error like this.

[hamidfzm]

@xiaonanln What do you mean by resource limit? btw I'm running this code on MacBookPro with lots of RAM and storage space

[xiaonanln]

things like max process num， open files， etc

dispatcher启动失败，和楼主老哥的问题描述类似，使用mongodb。 @xiaonanln

I have the same problem when executing the command, 'goworld start examples/unity_demo/'. then solved by executing the following command,"goworld build examples/unity_demo" someone can try it
