Kannel: ERROR: System error 98: Address already in use

Question

I cannot run kannel(an open source sms gateway) run properly. Everytime I try I get this error. ERROR: System error 98: Address already in use

Here is my kannel.conf

group = core
admin-port = 13000
admin-password = 123
status-password = 123
smsbox-port = 13003
wapbox-port = 13004
log-file = "/home/eclipse/kannel_core.log"
log-level = 1
wdp-interface-name = "*"

#group = smsc
#smsc = fake
#port = 1000

group = smsbox
bearerbox-host = 127.0.0.1
sendsms-port = 13013
log-file = "/home/eclipse/kannel_smsbox.log"
log-level = 1

group = wapbox
bearerbox-host = 127.0.0.1
log-file = "/home/eclipse/kannel_wapbox.log"

group = sendsms-user
username = 123
password = 123
user-allow-ip = "127.0.0.1"

group = sms-service
url="http://localhost/sms/send.php?sender=%s&&text=%t"
accept-x-kannel-headers = true

and the log file for the core:
