You need first to start bearerbox before starting smsbox.

Subject: SMSBOX not starting with PANIC

Hey All,

We run a kannel instances with multiple connections and to increase the 
throughput for each we found that we can set multiple instances for each 
connection

We have no issue when we set the instances to 5 however
we have an issue when we set that to 10, starting kannel service fails with the 
error below

2021-12-14 10:39:14 [4089406] [0] ERROR: connect to <127.0.0.1> failed

The kannel.conf  is

#*********************************************************************
# Core Config
#*********************************************************************
group = core
admin-port = 13000
smsbox-port = 13001
admin-password = XXXXXXXXX
admin-deny-ip = "*.*.*.*"
admin-allow-ip = "127.0.0.1"
wdp-interface-name = "*"
log-file = "/var/log/kannel/kannel.log"
log-level = 1
store-type = spool
store-location = "/var/kannel/spooled"
sms-resend-retry = 10
sms-outgoing-queue-limit = 10000000
box-allow-ip = "127.0.0.1"
box-deny-ip = "*.*.*.*"

#*********************************************************************
# SMS Box Config
#*********************************************************************
group = smsbox
bearerbox-host = localhost
sendsms-port = 13013
log-file = "/var/log/kannel/smsbox.log"
log-level = 1
mo-recode = true

include = "/etc/kannel.d/"

And each connection has config such as below

######################################################################
# operator X
######################################################################
group   = smsc
smsc    = smpp
host = 192.168.14.14
port = 9000
smsc-username = FOO
smsc-password = BAR
transceiver-mode = true
window = 1
throughput = 40
system-type = "SMPP"
smsc-id = operator_x
allowed-smsc-id = operator_x
log-level = 0
log-file = "/var/log/kannel/operator_x.log"
address-range = ""
interface-version = "34"
instances = 10

Is there a maximum number of connections we can have at the same at the same 
time?

Thanks
