[EBS 12.1.3] adstpall cannot terminate all processes.

Hi, experts

I always facing below issue.

[Issue]:

EBS 12.1.3

After clone a environment, the adstpall.sh cannot stop all processes.

below processes remains:

XXXX 28527 28522 0 XXXX 00:00:18 FNDLIBR

XXXX 28850 28527 0 XXXX 00:00:00 PALIBR

I have asked customer to try below action plan but no luck.

1. step AP tier and kill all remain processes.

2. relink.

    cd $FND_TOP/bin

　　$ adrelink.sh force=y "fnd FNDLIBR"

　　$ adrelink.sh force=y "fnd FNDSM"

　　$ adrelink.sh force=y "fnd FNDFS"

　　$ adrelink.sh force=y "fnd FNDCRM"

3. review "Concurrent Processing - Command-Line Utility OR Recovery Wizard (Doc ID 134007.1)",

   and recovery.

4. start AP tier and re-test this issue.

Anybody have opinion?
