[erlang-questions] 回复： About error enfile?

[yaohui]

ok, thanks.
  
   
out of socket memory says something.  

 I think you can keep watching /proc/sys/fs/file-nr and /proc/net/sockstat during test.

 dmesg print a lot log

Can you post the output of "dmesg" which might include some OS warning messages. 

 "416     0       4821388" is some time after this happened, right? It shows that there aren't many files open.

 cat /proc/sys/fs/file-nr result
 416     0       4821388
  
   
  ulimit -n 800000? 
  800000 < 1000K. 
 Is this the problem?
 What about cat /proc/sys/fs/file-nr?

 {error,enfile} this error represents the files tables is full (for the entire OS)
 but my kernel 
 ulimit -n 
 800000
 cat /proc/sys/fs/file-max 
 2215800 
  
 {error,enfile} is this error means other problem?
