Reporter: Róbert Ihász Assignee: Stuart Douglas Priority: Critical Labels: memory_leak, memoryleak Attachments: wildfly_memory_leak.PNG After a time the wildfly freeze hard. Cpu work at the maximum and memory is out. Only kill -9 can stop the entire application. I tried to monitor with Java VisualVM and it seems that the io.undertow.protocols.ssl.SslConduit$1 class growns too big. I attach a print screen from VisualVm. The log and console out are not shown any errors.
