Hello Unix gurus,

I have a Solaris 8 system on which since last few days we are noticing 0% idle state. When I checked with sar utility, I saw that process switching is very high. The output of sar -w is pasted below:

I am not sure if it has to do with any mis-configured kernal parameter. Please help me. Let me know in case you need anything else from system for more analysis.

Thanks a ton,
