Hey guys, I've been a long time lurker but this is my first post! I'm running Ubuntu 10.10 64bit, and I'm a newbie when it comes to networking.

My issue is that there seems to be a socket bound to a port blocking MongoDB from accessing it's usual port 27017. The strange thing that it was working just fine until recently and I can't figure out what I did to screw things up... I can make it use a different port but the reason why it can't bind to the default port and why I can't fix it is really bothering me. I've tried rebooting the machine even with nothing else running when I try to run Mongo is still blocked giving the following message:

Do I have some weird setting that's blocking the association of port bindings to the PID?
so sockstat..
ropes@ropes:~$ sockstat -p 27017
USER PROCESS PID PROTO SOURCE ADDRESS FOREIGN ADDRESS STATEI'm really confused, it seems like the socket isn't bound at all but Mongo still can't bind to the port, so there's some type of ghost binding?

I've pretty much been following this blog about tracking down port issues:
http://www.techrepublic.com/blog/security/list-open-ports-and-listening-services/443

but whatever is causing this issue is beyond my knowledge base.
Thanks for any help you guys can give!

解决方法：

Hey you probably found a solution already, but in case anyone else wants a quick fix here's a solution to find and kill the Mongo server.

Get the process list:
ps -eF | grep 'mongo\|PID'This will return the PIDs which can then be used to kill the process and hopefully close the sockets as well.
UID PID PPID C SZ RSS PSR STIME TTY TIME CMD
mongodb 1260 1 0 26316 4316 4 Mar29 ? 00:00:00 /usr/lib/mongodb/mongod --config /etc/mongodb.conf
ropes 19931 18808 0 2239 864 1 03:16 pts/2 00:00:00 grep --color=auto mongo\|PIDProblem solved..

awesome, thanks! i'm able to launch it now. you rock!
