MongoDB 在启动时安装简单的测试操作管理器 java.lang.OutOfMemoryError [英] MongoDB Install Simple Test Ops Manager java.lang.OutOfMemoryError on startup

问题描述

我刚刚安装了 MongoDB Ops Manager 的测试评估，并在启动备份 HTTP 服务器时出错:

I just installed a test evaluation of MongoDB Ops Manager and get an error on startup of the Backup HTTP server:

Migrate MMS data
   Running migrations...[  OK  ]
Start MMS server
   Instance 0 starting..........[  OK  ]
Start Backup HTTP Server
   Instance 0 starting.......[FAILED]

2015-05-07T14:00:32.107+0000 [main] gid  ERROR ServerMain:199 - Cannot start bslurp server [FATAL-EXITING] - instance: 0  - msg: unable to create new native thread
java.lang.OutOfMemoryError: unable to create new native thread

我似乎有很多记忆

[root@krh60621 ~]# free -m
             total       used       free     shared    buffers     cached
Mem:         15951       4588      11362          0        364       2021

我将最大进程数提高到无限制，看看这是否有帮助....

and I upped the max processes to unlimited to see if that would help....

[root@krh60621 ~]# ulimit -a

[root@krh60621 ~]# ps -eLF| grep -c java

[root@krh60621 ~]# ps -eLF| wc -l
1031

有什么想法吗???

推荐答案

当我们升级到 Ops Manager 1.8.0 时，我在 Test Ops Manager 部署中遇到了类似的问题.我最终向 MongoDB 支持开了一张票，这是我们问题的解决方案:

I encountered a similar issue in our Test Ops Manager deployment when we upgraded to Ops Manager 1.8.0. I ultimately opened up a ticket with MongoDB Support and this was the resolution for our issue:

Ops Manager 组件使用默认用户名 "mongodb-mms" 启动.请调整此用户的 ulimit 设置以匹配当前在 /etc/security/limits.d/99-mongodb-mms-automation-agent.conf 中定义的mongodb"用户的设置.

The Ops Manager components are launched using the default username "mongodb-mms". Please adjust the ulimit settings for this user to match those of the "mongodb" user, currently defined in /etc/security/limits.d/99-mongodb-mms-automation-agent.conf.

您可能希望在 /etc/security/limits.d/ 下为 mongodb-mms 用户添加一个单独的文件.

You may wish to add a separate file under /etc/security/limits.d/ for the mongodb-mms user.
