java.io.IOException：无法运行程序“git”：错误=11，资源暂时不可用

Question

Using GOCD pipeline. We have two nodes, one of which clones code fine, this older node does not. We are seeing Cannot run program "git": error=11, Resource temporarily unavailable in the logs. Is there some configuration I am able to check?

This issue was resolved by restarting the go agent. A new issue arouse but this issue was resolved by the following.

1. Login into GoCD UI.
2. Click on "Agents"
3. Select the agent which is required to be restarted
4. click on Disable button
5. refresh the page.
6. You will see that agent disabled and at the last in the list
7. Copy the "Agent Name". This is the host of agent. Login into this host with Cada credentials.
8. Run command : sudo su -
9. Now execute : sudo /etc/init.d/go-agent1 restart (Note : The last digit after agent will change as per Agents/"sandbox" value in the GoCD UI) Above command will restart the agent
10. Now go back to the GoCD UI, select the disabled agent and click on Enable.
11. Refresh the page, agent should be back in idle state.Restarting GoCD agents:
