Operating system name and version: Ubuntu 12.04.5 x64 3.2.0-105-generic
Version of smsd: Smsd v3.1.14
Smsd installed from: sources
Name and model of a modem / phone: FALCOM TANGO 55
Interface: serial to USB

Well, after nearly 8 years of good services, sms3 has failed once today.
Despite to have setup a lot of automatic failure detection that restarts sms3 when needed, it wasn't enough today.
Here is the log when sms3 wasn't running correctly (better tell the modem wasn't answreing correctly):

Then after a sms3 stop and start, everything is back OK:

When modem wasn't answering to AT+CSQ , tests about sms3 state where running without problem:

/bin/ps ax | grep -v grep | grep 'smsd -n MAINPROCESS'
28447 ?        Ss     0:34 /usr/local/bin/smsd -n MAINPROCESS -p/var/run/smsd.pid -i/var/run/smsd.working -uroot -gdialout -l/var/log/smsd.log

[ Select ]

/bin/ps ax | grep -v grep | grep 'GSM1_'
28448 ?        S     65:32 /usr/local/bin/smsd -n GSM1_______ -p/var/run/smsd.pid -i/var/run/smsd.working -uroot -gdialout -l/var/log/smsd.log

[ Select ]

/bin/ps ax | grep -v grep | grep '[smsd] <defunct>'

[ Select ]

What would be an option to detect this failure ?
Thanks in advance for your time.
(I think it is a sporadic failure, but I'd like to try to fix it)

Here is an option, taken from this post.

Alarmhandler:

#!/bin/bash

LOG="/var/log/smstools/alarmhandler.log"
CONTROLFILE="/var/lib/smsd/application/control"

# $1 the keyword ALARM
# $2 a date in the format yyyy-mm-dd
# $3 a time in the format hh:mm:ss
# $4 the alarm severity (1 digit number)
# $5 the modem name or SMSD
# $6 the alarm text

echo "$2 $3,$4, $5: $6" >> $LOG

if echo -n "$6" | grep "Modem is not ready to answer commands" >/dev/null; then

  if [ ! -f $CONTROLFILE ]
  then
    DATE=`date +"%Y-%m-%d %T"`
    echo "${DATE},1, $5: Alarmhandler created request for reset." >> $LOG
    echo "APPLICATION RESET 358401111111 $5 $DATE" > $CONTROLFILE
  fi
fi

'bash' Syntax Highlight powered by GeSHi

Create a cron job which regularly checks the existence of CONTROLFILE, and deletes it and restarts the smsd when required.

sms3 failure once (seems modem wasn't aswering)
