I successfuly upgraded to SLES 11 SP2 86_64, but when tried to install the CA ARCserve backup 11.5SP3, there was an issue with the kernel memory share. It keep failing because the system doesn't have enough resourse and can not share the memory? The system's memory is 24G and only 4G is used and there are 20G free memory?

It was working fine before I upgrade to SP2, any clue.
