<pre wrap="">I am evaluating nginx pop3 proxy function and encounter 1 problem. Here
is my setup:
OS: RedHat FC7 2.6.21-1.3194.fc7 #1 SMP Wed May 23 22:35:01 EDT 2007
i686 i686 i386 GNU/Linux
GCC: gcc version 4.1.2 20070502 (Red Hat 4.1.2-12)
Nginx version: 0.5.26
Config option: --with-debug --with-mail --with-select_module
Nginx config:
daemon on;
user root;
worker_processes 10;
error_log logs/error.log debug;
pid logs/nginx.pid;
#maximum total connections of each worker
events {
worker_connections 100;
# use select;
debug_connection 127.0.0.1;
}
mail {
auth_http localhost:8088/auth.php;
pop3_capabilities "TOP" "USER";
pop3_auth plain;
imap_capabilities "IMAP4rev1" "UIDPLUS";
#pop3 configuration
server {
listen 110;
protocol pop3;
proxy on;
}
}
Test case:
- A mailbox with message around 10M large
- Use telnet to port 110, issue the USER/PASS command to login
- Issue RETR 1 to download the 10M message
- Close the connection by pressing Ctrl-] then 'q' right after RETR
command is issued
At this time, Netstat shows that the connection from nginx to the
backend POP3 server remains connected.
Now, I repeat the above test case with "use select" turns on in
nginx.conf. This time, I don't see the connection to backend pop3
remains after my client connection to nginx is terminated in the middle.
I suspect this is something to do with epoll call?
I only did the test on POP3 proxy, not sure if it has the same behaviour
on HTTP.
Please let me know if you need more information.

Could you create debug logs for epoll and select cases, and send them to me ?
