Redmine

Hello,

When Exporting all columns in CSV more than 2000 issues with > 20 customs fields, if export is longer than 5min we don't get the CSV file.
Tested with Firefox 16 & 29 and IE8
Chrome is the exception : we get the file although export is longer than 5minutes (because Chrome send keep alive request to the server)

Environment :
Redmine version 2.4.2.stable
Ruby version 2.1.0-p0 (2013-12-25) [x86_64-linux]
Rails version 3.2.16
Environment production
Database adapter Mysql2

passenger-4.0.33
RedHat 6.2 x86_64

Apache HTTPD 2.2.15 Config :

MaxKeepAliveRequests 500
PassengerMinInstances 1
PassengerStartTimeout 180

Thanks for helping
