 and ulimit -n 1000000
  
 cat /proc/net/sockstat

UDPLITE: inuse 0
RAW: inuse 0
FRAG: inuse 0 memory 0
  
  cat /proc/sys/fs/file-nr

 =ERROR REPORT==== 18-May-2011::08:52:26 ===
Error in process <0.34.0> with exit value: {{badmatch,{error,enfile}},[{server,do_accept,1}]}
   
 dmesg  out of socket memory apper 
  
  
   
out of socket memory says something.  

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

  /proc/sys/fs/file-nr "416     0       4821388"  is right now, I'll do a test again while observing this parameter 
   
 dmesg print a lot log
 out of socket memory
  
    
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.

  It's a problem 800000 < 1000K,  but connections are less than 540k 
  
 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?

  I do a test C1000k, when connections reach to 540k, I got a error {badmatch,{error,enfile}}. 
 {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?
