             Summary: Slow HTTPS Upload provokes High CPU Load
                 Key: WFLY-4693
                 URL: https://issues.jboss.org/browse/WFLY-4693
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 9.0.0.CR1
            Reporter: Serge Mürset
            Assignee: Stuart Douglas


This issue is a reopen of https://issues.jboss.org/browse/UNDERTOW-345.

This Issue is not fixed with Wildfly 9.0 CR1 (contrary to what was indicated in above mentioned ticket). Issue is fixed when XNIO trunk (https://github.com/xnio/xnio)  is built and replaces XNIO 3.3.1 module.

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.
