Upgrade from 1.9.0 to 1.10.0 throws ECONNREFUSED

[zcmgyu]

I upgrade to wd 1.10.0 throws a lot of error relating to ECONNNREFUSED when call to Appium Server to get status. Though it throws error code, but it still works after 10 times retry.
Version 1.9.0 still work fine.

This is not wd.

This is Appium polling to see whether the server on the device has been installed and launched. It takes a while, but eventually works.

@imurchie Thanks Imurchie.
Though eventually works, but it would happen if I upgraded it to 1.10.0, isn't right? I just call to same Appium Server with different wd version (1.9.0 and 1.10.0 or 1.11.1). 1.9.0 version worked fine

[imurchie]

I'm not sure what you mean. It will happen, in varying degrees, in all versions of Appium.

@imurchie - I face the same issue and I hadn't observed this on the older versions of Appium.
Is this expected behaviour?
I see a delay of 50-60 seconds before the WEBDRIVERAGENT is successfully started.
