    Agent unreachable

    Hi,
    I have installed agent 10g on unix machine(HPUX-11.1) agent runs for 6-8 hrs
    after that it dies out and when i see the db through grid control it says agent unreachable but when grep for agent it shows up and running , iam not sure whats happening here.

    i think this is not agnet issue but OS issue.
    Agent is not able to run(edit file agntstmp.txt) because of OS settings.

    Check this BUG :- 6439387.
    bug is for solaris though...
