I posted an issue to the mysql dev forums last week with regards to an issue we are encountering. The issue as we understood it last week was simple...after some time (undetermined as of then) query results from the web app (a PHP/MySQL/Javascript Ajax app.) would come back all 'wonky.' Upon issuing a mysql-server restart the data would be fine, and query results back to normal. This morning I figured out how to replicate the issue. Issue a double request for the mysql result set. Due to the "Ajaxy" nature of my web app it isn't the same as a double HTTPRequest of POST, as it is requesting a result set back from the database twice in a row before the response is collected. We run Apache 2.2 on FreeBSD 6.1.x, I am currently running MySQL 5.0.x....given the fact that I can repeat and reproduce the problem by either hitting my refresh button twice, or by hitting my javascript/Ajax button twice before I get my first response....can anyone point me in a direction to narrow down why my code might be doing this? I am using PDO with prepared statements and MySQL stored procedures to produce my result sets... if you asked me yesterday, I'd have said I wasn't doing any thing that MySQL couldn't handle...but apparently that isn't the case...
