We have created an issue in Pivotal Tracker to manage this. Unfortunately, the Pivotal Tracker project is private so you may be unable to view the contents of the story.

The labels on this github issue will be updated when the story is started.

@sbromley07 Thanks for the report! Looking into this now.

sclevine avatar Dec 12 '17 16:12 sclevine

What version of CF Local do you have installed?

sclevine avatar Dec 12 '17 16:12 sclevine

0.18.0

sbromley07 avatar Dec 12 '17 16:12 sbromley07

Does the error reproduce every time you run cf local stage ...?

sclevine avatar Dec 12 '17 16:12 sclevine

Also, do you require an HTTP proxy to connect to the internet? Can you provide a sample app that I can build to help reproduce the failure?

sclevine avatar Dec 12 '17 16:12 sclevine

Its happening every time.

I don't have any HTTP proxies set up, but I am on a corporate network

sbromley07 avatar Dec 12 '17 16:12 sbromley07

Do you have outbound access to the public internet?

sclevine avatar Dec 12 '17 16:12 sclevine

I suspect that this is actually a bug in Go 1.9.1: https://github.com/golang/go/issues/21717

You may have Go 1.9.2 installed locally, but Go isn't necessary to run CF Local. Version 0.18.0 was compiled with Go 1.9.1, which suffers from that bug. I'm building a beta with 1.9.2 right now, and I'll attach it here in a minute.

sclevine avatar Dec 12 '17 16:12 sclevine

This should be fixed on master. I'll cut 0.19.0 soon.

In the meantime, can you try out this 0.19.0 RC?

sclevine avatar Dec 12 '17 22:12 sclevine

Getting a different exception now. Although it seems to include similar function calls.

I am able to hit the public internet from the network I'm on.

The fatal exception fatal error: sweep increased allocation count happens when the Go GC runs and ends up with more allocated memory instead of less allocated memory. It can be caused by a bug in the program, but usually only when there are data races.

I'm looking at https://github.com/golang/go/issues/22781 as a possible cause, and still trying to replicate the failure.

Let me know if this is working for you in v0.19.0. I am not able to reproduce this on Windows 10 Enterprise running in VMware Fusion.
