Redmine

Dear Forum,

In the past I had a similar error. At that time I tried to bulk update several hundreds of issues, but got a proxy error. We solved it with the help of the forum to do such updates through the ports 3001 and 3002 and I reset the time out for the apache server.
I installed via Bitnami installer

Environment:
Redmine version 3.0.2.stable
Ruby version 2.0.0-p645 (2015-04-13) [i386-mingw32]
Rails version 4.2.1
Environment production
Database adapter Mysql2
SCM:
Subversion 1.8.11
Git 1.9.5
Filesystem
Redmine plugins:
clipboard_image_paste 1.10
redmine_already_read 0.0.5
redmine_ckeditor 1.1.0
redmine_landing_page 0.1.0
redmine_last_updated_by_column 0.3.0
sidebar_hide 0.0.7

This time the error already occurs with a bulk update for only 15 issues. I get an

Internal Error
An error occurred on the page you are trying to access.
If you continue to experience problems please contact your Redmine administrator for assistance.
If you are the Redmine administrator please check your log files for details about the error.

Also using the ports 3001 or 3002 get the same error.
In the following the production.log with the part of the bulk update:

I hope someone can help me. Thank you for your time!
