Generic Agent Error when more then 4000 Tickets affected

[Monitor02]

Hello together,

I generate a new Generic Agent to delete older Tickets then four years.

But I get following Error message:

[Error][Kernel::System::ObjectManager::_DieWithError][534] Kernel::System::LinkObject::ITSMChange could not be loaded: Can't locate Kernel/System/LinkObject/ITSMChange.pm in @INC (@INC contains: /opt/otrs-4.0.14/Custom /opt/otrs-4.0.14/Kernel/cpan-lib /opt/otrs-4.0.14 /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /opt/otrs-4.0.14/Kernel/System/ObjectManager.pm line 192.

If I change the Date settings and affect only less then 4000 Tickets, the agent will run successfully.

But there is no ITSMChange.pm in Kernel/System/LinkObject. If I copy this file from an other System I get a other message:

Thanks for your help.
