Python 错误 OSError: [Errno 31] 链接太多

请参阅下面的错误消息，我在尝试使用 Python 的本机 os 库创建新目录时收到此错误消息.

See error message below, I get this while trying to create a new directory with Python's native os library.

...

File "files.py", line 93, in create_dir 
os.makedirs(d) 

File "/usr/lib/python2.7/os.py", line 150, in makedirs 
makedirs(head, mode) 

File "/usr/lib/python2.7/os.py", line 157, in makedirs 
mkdir(name, mode) 

OSError: [Errno 31] Too many links: '/var/lib/kaas/77520' 

我可以看到这个目录中已经有超过 32000 个目录

I can see that there are just above 32000 directories already in this directory

$ ll | wc -l
32001

操作系统级别对可以创建的目录数量有限制吗，或者是什么导致了这里的问题?还是这是 Python 的限制?

Is there a limit on the OS level for how many directories that can be created or what is causing the issue here? Or is this a Python limitation?

我运行的是 Ubuntu 12.04.4 LTS.
