Environment

Situation

• Linux Access Gateway installed as VMWare guest system with 1GB of memory and a virtual disk of 8 GB
• Using the standard installation process will generate the following partitions
           
  
• Cache Object Store (COS) partition of "3.91GB"
• root  => "2.1GB"
• boot  =>  "38MB"
• var   => "2.1GB
  
  

• File downloads through LAG slow down or freeze and will result into broken (truncated) files
• Files bigger than 520 MB cannot be downloaded

Resolution

The Linux Access Gateway has a minumum required of a 30GB disk as stated in the Novell Access Manager Installation Guide Section " Planning Your Partition Strategy". The recommended size is about 100GB. The COS partition should be at least "4x" as the maximum downloadable file size.
