Resolving vicidial issue Your session has been disabled

 

Introduction:

VICIdial is an enterprise class, open source, contact center suite in use by many large call centers around the world. VICIdial has a full featured predictive dialer.  It is capable of inbound, outbound, and blended phone call handling. 

  Issue : your session has been disabled

You may notice the message "you session has been disabled " under below conditions
1. During agent login to vicidial  agent portal
2. After successful login at frequent time its popups this message.

  Root cause 

Below are few root cause for the issue -your session has been disabled

1. Vicidial Admin /manager have forceful logged out the particular agent from admin interface.
2. Mysql/Maridb database crash for the table vicidial_live_agent
3. Crontab DB query -queues.
4. Lack of Memory in Server.

  Workaround

    Vicidial admin force logged out

     Make sure admin access are not misused, use strong password for admin, restrict admin rights .
     Make sure public access to dialer is secured , as vicidial admin API can triggered to logout agents.

    Database Table vicidial_live_agent crashed

run the below command to check any table crashed in the database.
mysqlcheck -u root -p --check --all-database

(note: if you have set a root password then enter ,or press enter if dont know the password run below command)

mysqlcheck -u cron -p1234 --check --all-database

If you have received below output then the particular table is crashed,  you need to repair.

asterisk.vicidial_live_agents
Error : Incorrect file format 'vicidial_live_agents'
error : Corrupt
Repair Command

Run the below commands to repair and optimie.
(note if root password is unknow use cron with password 1234)

mysqlcheck -u root -p --auto-repair --all-databases

mysqlcheck -u root -p --optimize --all-databases
Force Repair:

if the above command failed to repair the crashed tabled ,use the below command to force the repair

Login to mysql console

mysql -p
use asterisk;
repair table vicidial_live_agents table use_frm;
optimize table vicidial_live_agents table;

    Crontab DB query - queues.

    crontab entry script that is running at regular interval ,which is running a database query may cause this issue indirectly. ref link

solution: delete the TMM files in mysql data directory

search the .TMM files under /var/lib/mysql/asterisk/

similar to vicidial_live_agents.TMM

delete the file using rm -rf 
rm -rf ./var/lib/mysql/asterisk/vicidial_live_agents.TMM

Also run the below command to flush the DB table for entries older than 1 hour

/usr/share/astguiclient/AST_flush_DBqueue.pl --seconds=240 --session-flush -q

I'd recommend changing the DBflush to run every 4 minutes: Ref LInk

crontab -e
### flush queue DB table every hour for entries older than 1 hour (changed to 4 minutes)
1,5,9,13,17,21,25,29,33,37,41,45,49,53,57 * * * * /usr/share/astguiclient/AST_flush_DBqueue.pl --seconds=240 --session-flush -q

    Lack of System Memory

Check the Current usage of the memory in your system ,by typing top or htop command.

also run free -m to see current free ,used memory

Delete any cached memory by running below command

sync; echo 3 > /proc/sys/vm/drop_caches

you can schedule the above command to run every 30 min in crontab to delete cache at regular interval.

  Summary:

    Regular maintenance of vicidial like deleting old data's, recordings, Avoiding Overload, improper shutdown will avoid most of the vicidial issues
