Novell Access Manager 3.1 Linux Access Gateway
Novell Access Manager 3.1 Service Pack 3 applied
SLES 11 based Linux Access Gateway



After approximately 2 to 3 days of regular working activities, application accessed via Linux Access Gateway (LAG) starts to show pages where images are not fully downloaded. A restart of the novell-vmc service clear the problem that, however, comes back regularly after a while.

A lan trace captured between the browser ant the LAG shows a TCP Zero Window never recovered from the LAG side while downloading the images present in the web pages.


Service Pack 3 was recently applied on the LAG.


In order to fix the issue upgrade the LAG to Service Pack 3 Interim Release 2, or later, and then enable the use of the following touch file:

# touch /var/novell/.noFillThrottling

Restart "/etc/init.d/novell-vmc" service to make the touch file effective.
