在ssl模式下运行mesos时，我不断遇到分段错误。
回溯coredump后，我发现：

在运行mesos之前导出的环境变量包括：

以及用于运行mesos的命令：

mesos_master --ip=172.24.51.99  --advertise_ip=172.24.51.99 --hostname_lookup=false --acls=file:///opt/mesos/etc/acl.json --modules=file:///opt/mesos/etc/modules.json --port=5050 --quorum=3 --work_dir=/ghostcache2/mesos/registry --zk=zk://mycluster1.random.cluster.com:2181,mycluster2.random.cluster.com:2181,mycluster3.random.cluster.com:2181,mycluster4.random.cluster.com:2181,mycluster5.random.cluster.com:2181/mesos.mycluster --cluster=mycluster --hostname=mycluster2.random.cluster.com --offer_timeout=30secs --webui_dir=/opt/mesos/share/mesos/webui --whitelist=file:///opt/mesos/etc/whitelist --authenticate_agents=true --authenticators=crammd5 --authorizers=local --credentials=file:///opt/mesos/secrets/all_credentials.json --authenticate_frameworks=true

我试着将mesos（从1.7.0升级到1.9.0）、libevent（从2.0.21升级到2.1.8/2.1.12）升级到最新版本，但仍然没有成功。不知道我错过了什么。感谢您的帮助。
