Operating system name and version: Nagios (CentOS)
Version of smsd: 3.1
Smsd installed from: Make/Make install
Name and model of a modem / phone: WaveCom
Interface: USB

I am using Nagios to monitor servers. and send the alter by SMStool which works well when the receiver is one or two. but if we need to send out sms to multi-receiver (more than 10) at same moment. we found the message can't be sent out. but the log tells it's sent successfully. like the modem is jammed. after that, no message can be sent out. sometime, for 10-20 mins, some message can be sent out, some cannot. we tried the different brand of modem and different SMS tool. but the same problem.

this is our conf. would someone can give me some cules? Thanks a lot.

# Example smsd.conf. Read the manual for a description

devices = GSM1
logfile = /var/log/smsd.log
loglevel = 7
outgoing = /var/spool/sms/outgoing
checked = /var/spool/sms/checked
failed = /var/spool/sms/incoming
receive_before_send = no
keep_filename = no

[GSM1]
device = /dev/ttyUSB0
incoming = yes
#pin = 1111
mode = new
rtscts = yes
cs_convert = yes
smsc = 8613800210500
memory_start=0
report = no
send_delay =0
baudrate = 115200
