My website has been working without problems: www.dzwiek.org
and today one of the users reported he couldn't access a particular thread. I checked and I can't access it either:
http://dzwiek.org/threads/kpa-kemper-metal-profiles-sinmix.12100

it throws out this error:

Code: 
An exception occurred: Mysqli prepare error: MySQL server has gone away in /home4/milaszew/public_html/library/Zend/Db/Statement/Mysqli.php on line 77

The error is due to a timeout, which obviously shouldn't happen when loading a thread.

You may need to check in the database to see if there is anything unusual about that thread or the posts.

Are you running 1.2.4? That error may be hiding the actual error (which is probably related) and I believe this issue is fixed in 1.2.4.

Otherwise, I would have to recommend disabling add-ons and attempting to reconfirm it.

I just updated to 1.2.4 and it didn't fix it. I will investigate add-ons.

This is showing that add-ons are still enabled. It's not definitive that it's the add-on in question causing it, because it's just trying to access the DB and the connection has been closed. (So the issue has happened before hand.)

However, it generally indicates that something is being very slow and not accessing the DB, thus causing a DB timeout. An add-on that fetches link titles could do this for example.

Disable all add-ons again please and reconfirm. (Include the back trace then.)

Now when I disabled add ons using config.php the thread is loading up fine.
How can I trace which add-on is causing the problem?

With all add-ons disabled through config.php:

Add-ons are definitely not disabled in that last example.

You should disable all add-ons via the control panel and then enable them one by one until the large delay/error comes back.
