Resolution

1. Disable "Read ahead embedded images" in nwadm32. This setting can cause loops and high utilization due to access to sites that requires a cookie on the header after authentication. Read ahead will send the GET request before the browser sees the next page and this request does not contains a cookie. This setting will be remove in Novell BorderManager 3.9 as there is no more advantages to use it due to current web pages design.

2. Disable hyperthreading in the BIOS. Please refer to tid 10091810 to understand why this setting is very bad for Netware operative system and it has to be disable.

3. Fixed in bm38sp4_ir1.exe and above
