Describe the Scenario
Hi all.
Thank you for your time today. I'm having an issue with Bookstack where I am unable to export large books. My books contain many pages and these pages collectively contain hundreds of steps and images as I write in depth technical documentation. I initially received an "unknown error" but after enabling debugging, I can see the maximum execution time of 30 seconds is being exceeded.
I have found my way to issues #389 #1603 #1590 and #804
Per the comments in those tickets:
-I have changed the maximum execution time in my php.ini file from 30 to 3000.
-I have set my resource limit to -1 for unlimited resource use
-Checked and confirmed my server has 8gb of RAM available to it.
-Cleared my artisan cache
-Restarted my webserver through both a full system restart and by manually restarting appache via the command line using the command:
# /etc/init.d/apache2 restartThe issue still persists. However, I have noticed that despite having set the maximum execution time to 3000 seconds (fifty minutes) I notice BookStack will still give the error after just 30 seconds. Because of this I can only assume the php.ini file is either being ignored or overridden elsewhere. Is there any code in BookStack itself that could be causing this?
I have attached my debugging log file to this post and here are my version numbers. I installed BookStack into a completely fresh install of Ubuntu using the following commands found on the bookstack installation page. I experienced no issues during installation.
wget https://raw.githubusercontent.com/BookStackApp/devops/main/scripts/installation-ubuntu-22.04.shchmod a+x installation-ubuntu-22.04.shsudo ./installation-ubuntu-22.04.shHere are my versions:
Ubuntu 22.04.4 LTS
PHP Version: 8.1.2-1ubuntu2.14
BookStack Version: v24.02.3
Apache/2.4.52 (Ubuntu)
Here is a screenshot of the error:
I greatly appreciate any assistance with this and thank you for taking the time. I see this as a blocker and don't believe I'm able to resolve this myself.
