Thanks for the fix! < 2MB is definitely a much more reasonable amount of memory usage.

I'll take a closer look later tonight and get this merged.

Ola @xthexder, can we merge this?

[chaosbox]

@jpittis @xthexder
hi guys,
any feedback on this PR?
thanks

[jpittis]

This LGTM.

[pgeorgiev333]

Can you guys merge this and create a new release? This is pretty important as we cannot simulate network failures for longer periods of time.
Thanks in advance

[jpittis]

I'm pretty sure this needs a stub.Close().

[jpittis]

So I'm pretty sure this is good to merge now.

Any chance you can sanity check @xthexder?

Unfortunately, our company recently rolled out this contributor license agreement stuff so I can't merge this until the original contributor has clicked through the agreement. @chaosbox

I'm so sorry this has taken so long to ship, I'll release this as soon as we merge.

@jpittis I have accepted the CLA for the emailID tied to my public github account.

[jpittis]

I think you're going to have to change your commit to be authored by the same public email.

[xthexder]

This looks good to me.
I haven't really had much time to look over Toxiproxy recently, I may try to find some time over the holidays to do a pass and fix any outstanding issues.
