Ajax time out

[#1]

Hello,

one of my charts has a big calculation, which works fine for most product categories except a few that return a lot of rows. After exactly 60 seconds, the module (ajax) crashes displaying the 'Lost connection to server' dialog box.

I have not been able to find any 60 seconds timeout, in QVS console or IIS 7.

mem and cpu are fine and are not maxed out

any clue where else I should check? thanks

Environment:

Windows Server 2008 R2

IIS 7.5

QVS 11 SR6

64 bit
