Hello Emilio,
Did you check your PAM config?
Which Linux distribution do you have?

## Logging: (goes to syslog by default)
## 0 no logging
## 1 normal

## check backend:

Alive 10
#Client 30
Control "/opt/pound-2.5/etc/pound.socket"
..... after, there is a lot of virtualhost configuration!

thanks!

Hi,
Still, if you use RootJail parameter (send us your pound.conf) you should
check your pam config.
I'm sure it has nothing to do with IIS and pound. It's clearly linux limits
problem.

Hi, Piotr, Now I am running pound with user root:
r...@mymachine# /opt/pound-2.5/sbin/pound -f
/opt/pound-2.5/etc/pound.conf
r...@mymachine# ps -ef | grep pound
root 11864 1 0 08:59 ? 00:00:00 /opt/pound-2.5/sbin/pound

-f

at the same time I executed:
lsof -p 11865 | wc -l

and at the moment i can see on the logs:

I think it is problem of communication between pound (linux) and IIS
(Windows), when I restart pound the connections are Ok for minutes only.

Do you think that this is a pound problem?

Hello Emilio,
How do you run your pound?
My guess is that if you run it with su command you should check your pam
config for su.
Debian has it here: /etc/pam.d/su and it should contain uncomented line:
session required pam_limits.so
Works for me.

Yes modified.
I can see two diferents error messages:
1º)
Dec 30 10:24:46 lb pound: (b2ee0b90) e503 backend
192.168.1.10:80<http://192.168.1.10/>socket
create: Too many open files
and
2º)
Dec 30 11:36:35 sc02sns01 pound: HTTP accept: Too many open files
I think the first message is problem between pound and backend server,
the
server response with amessage when it try open a socket
and the second message I dn`t know, is it a response from the first
message?
or is it a problem with pound an the system?
I updated de ulimit -n for user that run pound (root) to:
ulimit -n
1009000
any suggestions?
Thanks
