Hi,
I kept playing around with the configuration files but still no luck. Today I
tried to send 20 sms to smppbox but my smppbox or kannel kept stalling again.
My system receives some 6 sms from my client and than it stalls for 1 minute or
so before it continues receiving the rest. Moreover, my client does not
receive all the deliveries back. It gets some 12 out of 20. I checked my log
files and I noticed several error and warning messages. In my smppbox.log I
get the following error and warning messages periodically.

Most of all the error about the "Broken pipe" alerts me, I don't know what that
means but it seems to be serious.
I don't know if that can be the reason.
My current configuration is as follows:
**** smskannel.conf ******
group = core
admin-port = 13000
smsbox-port = 13001
admin-password = bar
log-file = "/tmp/kannel.log"
log-level = 0

box-allow-ip = "127.0.0.1"
include = "/home/davit/workspace/kannel/gateway-revision-4837/gw/smsbox.conf"
include = "/home/davit/workspace/kannel/gateway-revision-4837/gw/smsc.conf"

# see sample smpplogins.txt
smpp-logins =

***************************************************
and my smpplogins.txt
foo bar VMA 245.127.0.0.1
client-02 password-02 vma 127.0.0.1
I would really appreciate any help and ideas. I don't know how to tackle this
problem ;)
Cheers,
Davit
