debugging an already running bash script

Code:
[root@server 10706]# ps -ef | grep rc
root     13903     1  0 08:56 ?        00:00:00 /usr/sbin/automount --timeout=60 /archive file /etc/auto_archive
root     10706     1  0 08:55 ?        00:00:00 /bin/bash /etc/rc.d/rc 3
root      2933 20071  0 19:38 pts/1    00:00:00 grep rc

Is there any way to debug the hanging rc script (pid 10706)?

tried pstree, the pid has no child.
tried /proc/10706, doesn't lead to where/why it is hanging
strace only have this output:

Code:
[root@server 10706]# strace -s1024 -f -p 10706
Process 10706 attached - interrupt to quit
write(1, "OK", 2

ideas? TIA.

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list. Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)). FILES
