> This issue is a reopen of https://issues.jboss.org/browse/UNDERTOW-345.
> This Issue is not fixed with Wildfly 9.0 CR1 when using the standard config without any timeouts set (however, above mentioned ticket indicates issue was fixed in Undertow 1.2.0.Beta6). 
> This is a major bug, as just one client with bad connectivity will cause a 100% CPU Load on Wildfly whilst the HTTPS upload is being read. It's also a real-world bug, as every note-worthy productive server will have at least one client with bad connectivity at any given time. Duration of the high CPU load directly correlates to the duration it takes the client to send all his POST data.
