Hi Test6405

the error 120 is just a client alert and can be a false positive (we've improved the detection with our latest developments so that such alert will be more effective from the next distribution on). Some info about it can be found here: http://www.lightstreamer.com/vb/showthread.php?t=354

About the error we've never seen anything like that.
Is such error strictly related with the freeze you're experiencing?
Can you post a snippet of your server log that shows the requests sent by IE6 during a "seession" where you saw such error?
Which kind of IE6 are you using? A standalone version or a complete version? (complete versions can be easily tested within a virtual machine, see http://www.microsoft.com/downloads/d...displaylang=en )

About the freeze,
is the CPU saturated when it happens?
which is the engine status when it happens?
Can you post a snippet of your server log that shows the requests sent by IE6 during a "seession" where you saw such freeze?
