             Summary: OpenSSL via Wildfly-OpenSSL crashes VM on application server shutdown when mod_cluster used
                 Key: WFLY-8753
                 URL: https://issues.jboss.org/browse/WFLY-8753
             Project: WildFly
          Issue Type: Bug
          Components: Security
    Affects Versions: 11.0.0.Beta1
         Environment: RHEL 7 x86_64
            Reporter: Michal Karm Babacek
            Assignee: Stuart Douglas
            Priority: Critical


Worker node with this mod_cluster and Elytron configuration [^standalone-ha.xml] keeps complaining on being unable to agree on a cipher suite with the Undertow balancer, whose Elytron configuration is identical, i.e. {code}
<server-ssl-contexts>
    <server-ssl-context name="serverSSLContext" providers="openssl" need-client-auth="false" key-managers="keyManager"  protocols="TLSv1.2" trust-managers="trustManager"/>
</server-ssl-contexts>
<client-ssl-contexts>
    <client-ssl-context name="clientSSLContext" providers="openssl" key-managers="clientKeyManager" protocols="TLSv1.2" trust-managers="trustManager"/>
</client-ssl-contexts>{code}

{code}
Full log: [^server.log].

I might or might not have it misconfigured, but what definitely should not happen is that when I try to shut the server down:
{code}
INFO  [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested via an OS signal
{code}
it crashes JVM (doublefree?):
{code}
# JRE version: Java(TM) SE Runtime Environment (8.0_121-b13) (build 1.8.0_121-b13)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.121-b13 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# C  [libcrypto.so.1.0.2h+0x117a64]  sk_pop_free+0x24
#
{code}
Core: [^hs_err_pid12281.log]

WDYT?
