Pfiles - Too Many file hanlder usage

807557Apr 12 2010 — edited Apr 18 2010

Hi,

We have been running a XMPP server. The clients connect to the server using TCP connection. We have been observing a higher number of file handler usage when compared to total number of sockets consumed. For example, we have 10,000 active TCP connection where as the 40,000 file descriptor usage.

I have also run the pfiles on the pid and found the following,

a) S_IFSOCK : we have 39k of S_IFSOCK allocation
b) No peername: we are observing file handler allocated with out the peername

 S_IFSOCK mode:0666 dev:276,0 ino:59589 uid:0 gid:0 size:0
      O_RDWR|O_NONBLOCK
	SOCK_STREAM
	SO_REUSEADDR,SO_SNDBUF(409600),SO_RCVBUF(49152),IP_NEXTHOP(0.192.0.0)
	sockname: AF_INET xx.xx.xx.xx  port: 5222

xx.xx.xx.xx - Local host ip address

c) Socket name "0.0.0.0":

S_IFSOCK mode:0666 dev:276,0 ino:43441 uid:0 gid:0 size:0
      O_RDWR|O_NONBLOCK
	SOCK_STREAM
	SO_REUSEADDR,SO_SNDBUF(409600),SO_RCVBUF(409600),IP_NEXTHOP(0.64.6.0)
	sockname: AF_INET 0.0.0.0  port: 0

Can someone explain the cause for such behavior.

Thanks in advance.

Nirmal
