[Asterisk-Users] PRI/E1: machine freeze/dies after a few calls

Hi all,

inside my * is a E400P. The machine is a PII 400Mhz with 256MB Ram. OS is
Debian woody. * is the newest cvs co.

I have written a little callgen script which make outgoing calls through my
*:

#! /bin/sh
set -e

n=$1            # Nummer
anz=$2          # Anzhal der Versuche
anz2=$3         # Kan?le
sle=$4          # Timeout bis zum n?chsten Versuch

if [ -z $4 ]; then
    sle=0
fi

s=1
i=1
while [ $s -le $anz ];do
    echo "$s try started..."
    while [ $i -le $anz2 ];do
        echo -e "Channel: Zap/g1/$n$i\nMaxRetries: 0\nContext:
callgen\nExtension: 1\nPriority: 1\nCallerid:334778\n" >
/var/spool/asterisk/outgoing/call.$i.$s

        sleep 2
        i=$((i + 1))
    done
    i=1
    echo "sleep for $sle sec....."
    sleep $sle
    s=$((s + 1))
done

The calls goes out over the first two ports and through a pri switch (teles)
they come back at the other two ports (3 and 4).
But after a few calls my machine is completly freezed! So that i have to
restart my machine.


Here're my extension.conf, zapata.conf and zaptel.conf:


---->extension.conf:

[pri1]
exten => _X.,1,SetAccount(pritest)
exten => _X.,2,Answer
exten => _X.,3,Wait(15)
exten => _X.,4,Hangup

[pri2]
exten => _X.,1,SetAccount(pritest)
exten => _X.,2,Answer
exten => _X.,3,Wait(15)
exten => _X.,4,Hangup

[pri3]
exten => _X.,1,SetAccount(pritest)
exten => _X.,2,Answer
exten => _X.,3,Wait(60)
exten => _X.,4,Hangup


[pri4]
exten => _X.,1,SetAccount(pritest)
exten => _X.,2,Answer
exten => _X.,3,Wait(60)
exten => _X.,4,Hangup


[callgen]
exten => 1,1,Wait(90)


---->zapata.conf:

Thanks for your help.

[Asterisk-Users] PRI/E1: machine freeze/dies after a few calls

Hi Thomas-

I didn't look closely at your shell script, but I wrote something similar in
Perl (and used shell to start each instance of it).  I had a few problems
too with a similar setup (although no machine lockups)

*  You are running quite a slow machine to run this script on many lines at
once - I found that I needed a P4, 2.4GHz to keep up with 120 channels
simultaneously (I had one system to send and one to receive, and very short
calls - 3 seconds).  How many instances are you running?  Are you doing
mySQL call logging?

*  I found that I could only initiate about 18 calls at exactly the same
moment without getting failed outbound call errors from asterisk, so I ended
up staggering the start times a little.

*  With lots of new calls, I had tons of framing errors on the receiving end
(and occasional D channel restarts) when routing calls through my DMS100
switch - do you have problems like this?  I think this problem is specific
to the Nortel switch however.

Suggest starting with -vvvvc and routing all output to a log file...??

regards
Scott
