Any other suggestions on this, it's spawning random tickets all the time now

[Johannes]

Hi can you give us some more information:
What did you do before the random error appeared?
Did you updated your instance to a new patchlevel?
Modified Sysconfigs? Modified files?

It seems to me that something is wrong with the defaults and they cant be written to disk (for an unknown reason).

It's a clean install and has happened since it was installed, i've never noticed the error myself but a ticket gets logged randomly that gives that error. No other files have been modified except apache conf.

[skullz]

I would try to

1. Set permission

Code: Select all

/opt/otrs/bin/otrs.SetPermissions.pl

2. Delete cache

Code: Select all

/opt/otrs/bin/otrs.Cosonle.pl Maint::Cache::Delete
/opt/otrs/bin/otrs.Cosonle.pl Maint::Loader::CacheCleanup

3. Restart webserver

4. Delete everything under /opt/otrs/var/tmp/

Good luck

[plattnat]

So i did that and now i'm getting this;

[cilap]

it is a clean install, means no prior data was in the DataBase? right?

also can you please share

Code: Select all

uname -a

Code: Select all

cat /etc/issue

Code: Select all

sudo df -h

Code: Select all

sudo mount 

[root]

Code: Select all

cat /etc/issue

Really? What should be the reason to see the "prelogin message and identification file"?

Hi,

I redacted your post and removed your hostname from it.

It was not my intention to worry you, but I do not seen any reason for any of the questions. But maybe I'm not experienced enough.

- Roy

[plattnat]

Aren't you on of the developers of the software Roy?

[cilap]

/etc/issue is containing your distribution name, nothing to worry about.
From your kernel it looks like it is CentOS8

I am not that deep in perl, but deep in software systems. It looks for me that either the serialization (writing data to disk) or the deserialization (reading data from disk) is failing.

To break it further down:
do you face any issues e.g. on writing to your disks with high load or with long running threads?

I had in the past issues with xfs on virtual environments. Is your environment a virtual guest? If so what type?

also would like to know

Code: Select all

sudo a2query -M

Hi,
sorry for the delay. Thank you for the explanation.
Can you post the output of /opt/otrs/bin/otrs.CheckModules.pl --all

Thank you

Edit:
And the output of:
/opt/otrs/bin/otrs.Console.pl Maint::Daemon::Summary

So i did that and now i'm getting this;

Thanks for the info.
Except for the loader cache cleanup, everything seems to be fine.

Another question:
Does this error occur at a certain interval?
Like every Sunday 2 a.m or something

I digged into the code and would say that we don't have to look at your OS at all.

But I would assume that at some time, there was a missing perl dependency or something is not 100% correct with your Sysconfig.

The issue somewhat related to the DefaultSettingListGet method. Which is called every time the sysconfig is read. To save some calls the cache is also updated with any call of this method.

It basically parses the sysconfig (all of it) from the database. The db stores the original XML values from your Kernel/Config/Files/XML directory and the parsed YAML values.

We had issues in the past before when YAML::XS was not installed at the point of installation. It could also be related to the XML parser or just a faulty sysconfig entry.

Can I suggest that you dump the following database tables:

- sysconfig_default
- sysconfig_default_version
- sysconfig_deployment
- sysconfig_deployment_lock
- sysconfig_modified
- sysconfig_modified_version

If you want us to dig deeper into this, send the zip compressed dump via mail to bugreport@znuny.com .
We try to replicate the error on our side. I tried it yesterday but could not trigger the error.

I can also offer you to have a look on your instance if you can provide some details to contact you, timezone and availability via mail.

Thanks
Johannes

Perfect. I can reproduce the error.
We dig into it.

[Johannes]

The issue is resolved.
We could only reproduce it on Rocky Linux. After we updated the Perl Module "Storable" to version 3.25 it disappeared.

What we did in short to update the module:
asRoot> cpanm Storable

Make sure you have the needed dependencies installed, like gcc and make
asRoot>dnf install gcc make cpanminus

You can remove them after the update if don't need them elsewhere.


We could not find an difference between the actual sysconfig settings or what was stored in the database.

Thanks for all the help. Marking as solved

I got the same error and when I checked I found that the supportdatacollector/pluginasynchronous contained a folder called znuny and not a folder called otrs. I have copied the znuny folder to a new folder called otrs and it fixed 3 problems at the same time.
- sending email attachments worked again
- calendar overview showed calendar items again
- support data collector worked again
