Problem to download large files when Sandblast Appliance is set as ICAP Server

[Leonardo_Ferrei]

Hello Guys,

We set the Sandblast Appliance as ICAP Server for a Fortigate gateway. The traffic is redirected as expected and the sandblast appliance is doing its job, except by large files (I've noticed files bigger than 400MB)

The users are unable to download any file bigger than 4000MB when the ICAP server is set. If I stop the icap process from sandblast appliance they are able to download their files.

Did anyone get the same problem?

SANDBLAST APPLIANCE = R80.20 Jumbo Take 47
MAXIMUM FILE SIZE FOR EMULATION = 15000KB (default)
ALL CONFIGURATION SET TO FAIL OPEN
THE USERS GET A BROWSER MESSAGE = An ICAP error was encountered while handling the request.

Best regards,
Leonardo Santos
