I was able to reproduce same problem in bboth test and production now, but in last 3 months when I was tetsing problem never occured, I created a ticket with Oracle, have not yet ggotten any response.
I am not being mislead. After mounting startup was hung (I not showing any output), I was running it in sqlplus. From other sqlplus I could connect to database without problem, so my users who are running third party application were running fine while Oracle startup was keeping me in suspense.
