Hi,
I have an application that is running fine on two different machines, but when I ported the code to a third machine, it doesn't seem to work. More specifically, for users with a significant amount of info, it seems to stop working. All the functionality seems to be working properly on a small test set, but with a larger set I get the following error:
AssociatedAp Load (0.000000) SystemExit: exit: SELECT * FROM associated_aps WHERE (mac = '00:0D:67:00:62:D3') ORDER BY date DESC LIMIT 1

Rendering /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.2/lib/ action_controller/templates/rescues/layout.rhtml (500 Internal Error)
The only difference between the machine where I get the error and the others is that I'm running Rails through Apache on the one with the errors. Here is what I get in the apache log when the crash happens:
[Mon Jun 11 13:13:07 2007] [error] [client 64.230.66.6] Premature end of script headers: dispatch.fcgi, referer: http://209.87.xxx.xxx/
The strange thing is that the SQL query that it crashes on executes several times on the same request before it crashes. Has anybody had a similar experience, or have any ideas as to what the issue might be?
Thanks,
Simon
