I wrote a simple server and client using dRuby. on client side, I executed about 200 simultaneous instances of client to see how my server does. I noticed on client side, I am getting DRb::DRbConnError while server is still up. Also I had DRb::DRbConnError when I executed client and server was not up. What I am trying to accomplish is to differentiate between this two types of error. Would anybody please help? Thanks, Mohammad
