service asterisk status
asterisk dead but subsys locked

Exact same thing happening to my server on Wable.

Their networking can be wonky. Have you tried hard-coding your DNS entries??

 

[wa4zlw]

My synagogue pbx died sometime yesterday and i had them reboot it to no avail. I will have to go over and check it out. DNS should be fine as everything else there is working

 

[krzykat]

I've written a script that automatically checks if asterisk has died, and if it has, it starts it back up and shoots out an e-mail.

I'd rather have this issue of why safe_asterisk doesn't kick it back up automatically. If you'd like the script, let me know and I'll be glad to provide it.

Curious ... is your instance in NY, Dallas, or Seattle

Dallas.

I am using only one trunk on this server; IAX, at voip.ms. I replaced the server name with the IP address to see what happens.

This is a test server, basically evaluating Wable. It's not doing so well

 

[krzykat]

I'm doing the same - I've got 9 servers there to test - mine that has that issue is also in Dallas. The kick script that I've made makes things work, but that's to the point to build any serious infrastructure on. I've just placed a copy of one with an issue in Dallas on NY to see what happens.

I like their speed, backups, and pricing, but it needs to be up without issues - still evaluating.

 

[wardmundy]

And they kinda give you the Soup Nazi treatment if you complain

 

[Uncle Robin]

Considering the price ($8.00/mo), I didn't set my expectations very high. Besides the asterisk randomly stopping, Wable seems pretty good.

There's always Digital Ocean for $5 a month if Wable gets too painful (includes $10 credit to play).

 

[krzykat]

Is Digital Ocean solid enough to run business class VoIP server from?

 

[Uncle Robin]

I looked at Digital Ocean and liked what I saw. I passed on them this round because I wanted a data center preferably in the midwest (I'm near St. Louis).

We've never had a problem. And their snapshot capability is awesome for (free) backups. Also makes it easy to scale up.

Scale up is one of the reasons I was looking at Wable. I figure I've got a Prox at colo for backup failover, and then wanted a scalable cloud based VPS and was thinking Wable would work. I guess I'll do an install at Digital Ocean and put them through the paces.

 

[wa4zlw]

two items...

1. false alarm...seems HVAC guy was around yesterday and the PBX was powered off!
2. Digital Ocean - works very well. my friend and I are using it (He more for business). He's in a SFO instance and I'm in a NYC instance. He's located in Australia till July and also has folks in the Philippines using it. Their support has been pretty good too.
Price is right and the connectivity excellent. 1ms hop to Voip.MS in NYC from NYC D.O instance which means probably in the same data center.

For anyone wanting the script to make sure asterisk is running and kick it back up if its not:

astcheck (place in /etc ... or wherever you like called from crontab)

#!/bin/bash

# WARNING::If working on server, set value = 1 to deactivate check service
deactivate=0

service=asterisk

# Should we skip the check?
if [ $deactivate -eq 0 ];
then
  ERRCD=$(ps cax | grep $service | wc -l)
else
  ERRCD=2
fi

# Run the Check
if [ "$ERRCD" -lt 2 ];
then

#       echo "[$service] is crippled running at $(ps -ef | grep -v grep | grep $service | wc -l)"
#       ERRMSG="[$service] is crippled running at $(ps -ef | grep -v grep | $service | wc -l)"
        ERRMSG="[$service] is crippled with run count [$ERRCD]of[2]"

        #/etc/init.d/$service restart
        #/usr/local/sbin/amportal restart
        RESTARTMSG=$(amportal restart)

        # $Company & $SITE variables are for populating the alert e-mail
        EMAIL='[email protected]'
        DATE=`date "+%m-%d-%Y %H:%M"`
        HOST=`hostname`

        # Message Formating
        MSG="[$DATE] Asterisk has stopped prematurely which resulted in a failure on host [$HOST].\n"
  MSG="$MSG Error=[$ERRMSG] .... ATTEMPTING RESTART!\n$RESTARTMSG"

  # log
        echo "---------------------------------">> /var/log/asterisk/asteriskfailure.log
        echo -e "$MSG" >> /var/log/asterisk/asteriskfailure.log

        # Send an email
        echo -e "$MSG" | mail -r 'urgent<[email protected]>' -s " ASTERISK DIED - on host [$HOST] ... RESTARTING" "$EMAIL"

# =========================================================================
fi

Of course, add the script to /etc/crontab

# Check if asterisk is running
* * * * * root /etc/astcheck

This runs the script astcheck every minute to make sure its working properly. If it isn't, it restarts it and sends you an e-mail.

@krzykat Mind if we add a GPL and copyright notice for you and add it to Incredible PBX??

 

[krzykat]

Uncle Robin and I have been working with Wable, and I'm hoping we get a resolution soon, but right now, I am squarely placing the blame on them - and probably just their Dallas Node. Both of us are experiencing asterisk failure at the same minute. If anyone else has a Dallas Node PBX with Wable, let us know.

Meanwhile, I'm trying out DO as recommended and so far, so good.
