*操作系统信息*
|
||
{code:java}
|
||
CentOS Linux release 7.4.1708 (Core)
|
||
Linux version 3.10.0-693.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Tue Aug 22 21:09:27 UTC 2017
|
||
systemd 219
|
||
{code}
|
||
*现象*
|
||
* systemctl and journalctl hang or fail ，导致Flink任务及其他java应用无法有效启动。
|
||
* 10.111.200. 220/229 ，目前现场未恢复，查看系统/var/log/message出现异常信息；
|
||
* 操作系统层面systemd 针对该问题，已通过patch包方式修复，由hang住修改为提示异常信息。参考链接：[https://access.redhat.com/solutions/3096191]

||
|
||
{code:java}
|
||
cat /var/log/messages |grep 'pid >= 1' -A 5 -B 30 {code}

|
||
|
||
*考虑方案*
|
||
* Galaxy 尝试复现Systemd hang 现象，后续验证Patch包，是否解决Systemd 无法启动问题
|
||
* 工程部可以提供操作系统的Patch更新包
