I just recently completed an upgrade from 1.90 to 2.0. Everything seems to be working as intended, but I am unable to Display Tokens for some surveys. I can't quite seem to figure out the pattern, but some surveys work and others don't. When the issue happens I am sent to a HTTP 500 page after clicking Display Tokens. Can you tell me what the SQL that is used to run for the 'Display Tokens' page or what file I might find it in? I want to determine if it is a problem with the table/data itself or something like along the lines of a timeout. Any other ideas are greatly appreciated.

Thanks,
Kyle

First step would be to activate debug mode in /application/config/config.php - you should get a more detailed error then.

Thank you, that was very helpful. After turning debugging to 2 and SQL Logging on I saw the following error, "Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 515 bytes) in C:\inetpub\wwwroot\limesurvey\framework\db\CDbCommand.php on line 506". I then increased the php memory allocation from 128M to 1024M which solved the problem for all but one of my surveys. The problem survey has more than 90,000 tokens. Since 1G seems like a lot to allocate to php is it safe to assume that there must be a memory leak somewhere or is allocating this much memory normal?

Thanks,
Kyle

Can you try and update to the latest build of 2.0+ and see if the issue still exists?
I just created a survey with 10,000 tokens and had no problems at all (memory limit at 80MB).
What PHP version are you using? Maybe your PHP version has a bug leaking memory.

I just updated to the most recent build (130929) and was unable to view tokens on a table with 50,000 without significantly increasing the php memory limit. I will continue to investigate, but it appears there must be a leak somewhere or a bug in php.

Sorry, I meant 100,000 tokens (which I created). What PHP version are you using?

Well, latest PHP version is 5.5.4 - I would try a PHP upgrade (or to countercheck any different version would do) first.

We are currently running on IIS and using MS-SQL. Since LS requires SQL PDO drivers, I believe that php 5.4 is the latest version that includes these drivers.

And you are already running 5.4.19? Or an earlier 5.4 version?
