[GSS](7.1.z) UNDERTOW-1231/UNDERTOW-1179 - Deadlock AbstractFramedChannel when notifyClosed and markStreamBroken are called related to Http2Channel

    XMLWordPrintable

Details

    Description

      Hello,
      we are using Wildfly 10.1.0.Final Full Profile for a production app.

      Because of XNIO-276, where in our case the CPU load went around every 3 weeks to 100%, we update in May our XNIO library to 3.4.5 and our Undertow server to 1.4.14.

      Since around 2 month we are seeing deadlocks in undertow like the one in UNDERTOW-1074. So we updated around a month to Undertow 1.4.20 because we though according to the issue it should be fixed in 1.4.15 unfortunately we are still seeing these deadlocks.

      I attached 3 stacktraces from our system.

      This bug is related to: UNDERTOW-1074
