OTRS 6.5.2 Error "Browser too old" returns every 2 Mondays

Hi.
My name is Emanuele and my English is very poor, I apologize for this.
I've search for error "Browser too old" on this comunity and I found many comands that helped me fixing this issue (thank you all for this!)

On the first time this error appeared I ran theese commands:

Code: Select all

# Stop services
sudo su
etc/init.d/cron stop
/etc/init.d/postfix stop
/etc/init.d/apache2 stop

# Stop OTRS
sudo su otrs
cd /opt/otrs/
bin/Cron.sh stop
bin/otrs.Daemon.pl stop

#Setting permissions
/opt/znuny-6.5.2/bin/otrs.SetPermissions.pl

#Recreate symlink
rm /opt/otrs
ln -s /opt/znuny-6.5.2 /opt/otrs

#Check modules
/opt/otrs/bin/otrs.CheckModules.pl –all
apt-get install -y libcpan-audit-perl

#Setting permissions

/opt/otrs/bin/otrs.Console.pl Maint::Config::Rebuild --cleanup

#Restart services
sudo su
/etc/init.d/cron start
/etc/init.d/postfix start
/etc/init.d/apache2 start

#Restarti OTRS
su otrs
cd /opt/otrs
bin/otrs.Daemon.pl start
bin/Cron.sh start

This happend on December, the issue was solved but after 2 weeks, on monday morning, the error had returned, ran same comands, issue fixed...

So, how can i check what is the cause of this problem or how can I "protect" OTRS from being broken by other operations such as Backups or Updates?

I would check any cron that perform update / reset someting..

Code: Select all

crontab -l -u root
crontab -l -u anyothersuser

I think this is a config rebuild.

When the error shows up, please check the Browser Console.
There will be missing JS Files (Error 404).

My guess is:
the automated sysconfig rebuild / check rebuilds the sysconfig and the error comes up.

You have may have success running bin/otrs.Console.pl Maint::Config::Rebuild --cleanup
This may solve the issue.

But it would be helpful to get the missing JS file from the console, to fix it for sure.

Thank you very much to everyone.

"crontab -l -u " was very usefull, but we didnt found any cron that could be linked with the issue.

We are currently investigating and next time the incident will appeare we will check for missing JS files.

Hello,

the problem seems to be caused by the OTRS cache that occupied all diskspace.

Is it possible to schedule a cache cleaning every week or it will brake te otrs services?

The command, could be this?
perl bin/otrs.Console.pl Maint::Cache::Delete

Hi,

Isn't it more of a problem of server administration? Monitor your disk space on all relevant partitions and too small disks?
The application cache of Znuny (6.5.2 is not an OTRS) is deleted by default once a week.
