[initandlisten] pthread_create Failed: errno:11 Resource temporarily unavailable
[initandlisten] can't create new thread,closing connection

我得出的结论是,我需要提高1024的“ulimit -u”或“Max processes”设置,并且在使用web前端时(不确定如何检查),用量可能超过了.

我编辑了/etc/security/limits.conf来添加最后两行(前两行已经存在)：

*                soft    nofile          350000
*                hard    nofile          350000
*                soft    nproc           30000
*                hard    nproc           30000

然后我重新启动了系统(BTW我应该这样做,还是应该重启mongod服务？)

重启后,查看mongod进程的进程限制,似乎忽略了软限制：

根据/etc/security/limits.conf文件,我预计“最大处理”硬限制和软限制将在30000,但只有硬盘限制.

我究竟做错了什么？

我在AWS EC2上运行Amazon Linux.

bash-4.1$cat /etc/*-release
