mongodb: pthread_create失败:错误号:11

我想在我的vServer (CentOS 6)上运行sharelatex。我安装了所有东西，但是sharelatex启动不了。mongod.log在接受一些连接后表示：
2015-02-12T12:04:30.971+0100 [initandlisten] pthread_create failed: errno:11 Resource temporarily unavailable
2015-02-12T12:04:30.971+0100 [initandlisten] can't create new thread, closing connection我已经增加了ulimits：
[root@vServer]# ulimit -a
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 256270
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 21000

cpu time (seconds, -t) unlimited
max user processes (-u) 256270
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited有谁可以帮我？
编辑:我还检查了mongod进程的限制：
[root@vServer]# cat //proc/552/limits
Limit Soft Limit Hard Limit Units
Max cpu time unlimited unlimited seconds
Max file size unlimited unlimited bytes
Max data size unlimited unlimited bytes
Max stack size 10485760 unlimited bytes
Max core file size 0 unlimited bytes
Max resident set unlimited unlimited bytes
Max processes 62848 62848 processes
Max open files 21000 21000 files
Max locked memory 65536 65536 bytes
Max address space unlimited unlimited bytes
Max file locks unlimited unlimited locks

Max msgqueue size 819200 819200 bytes
Max nice priority 0 0

下面是ulimit的输出：
[root@vServer]# ulimit -Sa

file locks (-x) unlimited但如您所见，我是以root用户身份登录的。不应该显示cat //proc/552/限制进程的实际限制吗？

我在使用mongodb时遇到了/proc/sys/vm/max_map_count内核参数的问题。基本上，mongodb正在尝试分配超过65k的内存映射，这是常用的内核限制。
当遇到此问题时，出现的错误与您发布的涉及pthread_create失败的错误相同。为了解决这个问题，我以root用户身份执行了以下操作：
echo 2048000 > /proc/sys/vm/max_map_count无论这是否有效，我强烈建议在mongodb pid上使用strace来尝试查看它的失败之处。我不认为您看到的错误消息一定会将您引向正确的方向。
