@ -238,6 +238,19 @@ Some platforms do not support all Puma features.
* **JRuby**, **Windows**: server sockets are not seamless on restart, they must be closed and reopened. These platforms have no way to pass descriptors into a new process that is exposed to Ruby. Also, cluster mode is not supported due to a lack of fork(2).
* **Windows**: daemon mode is not supported due to a lack of fork(2).
## Known Bugs
For MRI versions 2.2.7, 2.2.8, 2.2.9, 2.2.10 2.3.4 and 2.4.1, you may see ```stream closed in another thread (IOError)```. It may be caused by a [Ruby bug](https://bugs.ruby-lang.org/issues/13632). It can be fixed with the gem https://rubygems.org/gems/stopgap_13632:
```ruby
if %w(2.2.7 2.2.8 2.2.9 2.2.10 2.3.4 2.4.1).include? RUBY_VERSION
begin
require 'stopgap_13632'
rescue LoadError
end
end
```
## Deployment
Puma has support for Capistrano with an [external gem](https://github.com/seuros/capistrano-puma).
