Iplanet 6.0 SP8 log warnings

Question

I am running iplanet 6.0 SP8 in a Windows 2000 Advanced Server enviroment - Quad Processor, 4 GB Memory. We are having problems with images not showing up and I am getting a hand full of 404's - Not Founds. A simpe refresh usually fixes the problem.
Below are some of the warning logs, obj.conf file and magnus.conf file
I have seen several similar posts but I have not found any definate solutions. If someone could point me in the right direction that would be greatly appreciated. We recently were running IIS 6.0 without any problems besides performance side.

I can't explain what's happening, but something seems to be going wrong with the Web Server file cache. On Windows, the Web Server file cache normally copies files to a temporary directory and then uses the Win32 TransmitFile call to send them.
Can you check the file cache's temporary directory? If you haven't specifically configured another location, this should be located at %TEMP%\netscape. Specifically, check to see if there's free space on the disk. If it appears there's lots of free space, you can try stopping Web Server, removing the directory, and starting Web Server.
If nothing seems wrong with the file cache's temporary directory and removing it doesn't help, you can try adding the following lines to the config/nsfc.conf file:
CopyFiles=false
TransmitFile=falseThe above lines prevent Web Server from copying files to the temporary directory and disable the use of TransmitFile.
Please let us know if you make any progress.
