can't reproduce this bug.

Turned on debugging and have attached the result, hope this helps.

Maybe somethnig with a big survey ? 2100 parameters seems strange .

please, upload this template to a 2.06 and let us know if the same problem happen.

2.06+ 160129 running same DB PHP and IIS deletes without an error.

@LouiGac: it's something with lime_settings_global

With last_question_gid_user, last_question_user etc ....

Maybe
$criteria = new CDbCriteria;
$criteria->addInCondition('last_question_gid_user',$gidOfThisSrvey);
SettingsGlobal::model()->deleteAll($criteria);

Resolving IIS bugs is not a priority, unless IIS users make a donation.
so we'll resolve this bug when we'll have time.

If you don't want to fix : update status to new and "de assign" you :)

This part must be moved in model : RC/Plugin can delete survey too.

And must delete for all user ....

@Drewskie : you set private ? We can open it for other user ?

There are another issue here too :
lastquestion{$otherUser}
and
last_questiongid{$otherUser}
is not deleted.

Deleted only for actual user

Another one : is surveyid is 18, you delete queXMLSectionHeight (for example)

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=17270
