Hello all, we have solved this nasty issue switching from apache2-mpm-prefork to apache2-mpm-worker, tested on both Ubutu 10.04 and Ubuntu 12.04 (64 bit arch). It has been quite hard to figure it out! For the moment I cannot say from where the bug is generated: apache2, mod_perl or JSON ? If someone among you has a working configuration with multiple OTRS instances on Apache2-mpm-prefork under Ubuntu 10.04 or 12.04 (with "PerlOptions +Parent") plese let me know, I'd like to do some in depth configuration analysis.

Hello, we have two OTRS 3.1.8 instances running fine on Ubuntu 10.04 64 bit, with 2 Apache Virtual Hosts configured with the "PerlOptions +Parent" option.

Today I've upgraded one of the instances to version 3.2.6, upgrade went well with no errors, but now from the "Create New Request by Email" page, after selecting the From Queue we get a Browser error saying this:

Error during AJAX communication. Status: error, Error: Internal Server Error

and in the Apache Error log for the Virtual Host this is logged:

[Mon May 06 16:30:52 2013] [error] encountered object 'false', but neither allow_blessed nor convert_blessed settings are enabled at /opt/otrspath1/Kernel/System/JSON.pm line 106.\n

and the Operator pull down menu is not populated at all.

The Perl modules check is OK. Is this a known issue ? May be related to the multiple instances configuration ?

Thanks in advance for your support. Best regards, Luca
