Process exiting status in Oracle Application R12

Issue:
======
a) Unable to launch the application or Home page hangs in Oracle Application Release R12
b) If you check the services on the web/Admin node, you can see process
ps -ef | grep -i exiting
- 647302 – - – exiting
- 708754 – - – exiting
- 925856 – - – exiting
- 983252 – - – exiting

You can’t kill these process also
Only workaround is rebooting the box and start the services and it works fine.
This Issue will occur again after 2 weeks or less.

Cause:
=======
pid directories are placed on shared mount point.
Solution:
=========
a) Make sure all your pid variables are pointing to local disk in Context File…
s_lock_pid_dir
s_pids_dir
s_web_pid_file
b) Change in all the nodes and run Autoconfig.
Note:
It is always better to keep the $INST_TOP on local disk to avoid performance Issues.
