bug? net-ssh 2.0.11, MRI 1.8.7 on linux, ssh connections connect then eventually go into CLOSE_WAIT state

[Elijah Wright]

Hi guys,

I've got a user (inconveniently, in Poland, so major time zone difference) who's having trouble doing deploys to one of our multi-host rails environments.

Basically, when he runs cap qa deploy, ssh connections connect then eventually go into CLOSE_WAIT state. Hang, boom. Not fun.

I've managed to eliminate most of the possibles - multiple ssh keys, crap system ssh on his end, on the deployment end, etc - and think there might be a bug of some sort lurking here.

He can ssh to the hosts he's trying to deploy to while he's trying to deploy (as they're failing / falling to the icky CLOSE_WAIT state..), and I can deploy to them perfectly adequately, so I think I've ruled out server issues and *mostly* ruled out key issues on his local host.

How would folks-in-the-know like us to proceed with data collection, and what can you think of that might cause this kind of a failure?

thanks,

Elijah,

This may be part of it? .. have a read of this, and see if it fits https://capistrano.lighthouseapp.com/projects/8716/tickets/79-capistrano-hangs-on-shell-command-for-many-computers-on-ruby-186-p368#ticket-79-24

thanks - I've passed this along to the developer having the issues, and he's going to compare the notes with his running environment....

Indeed, this seems to have been the issue, or at least closely related - the dev guy in question built/installed REE 05/20/09, and the problem went away.  Sounds like a regression in 1.8.7, indeed.  (Everybody else is either using 1.8.6pl111-pl287, or REE of some version...)

Elijah,

 Good to have more ammo for the ticket, we haven't as yet found a solution to this yet.
