To tell you guys the truth, i panicked when this happened to me because i have never been a deadly situation like this before. I use to be that cautious admin that did only what he had to until i got lazier and decided to write more and more and more scripts.
anyway, the system was SunOS 5.8. and since i loved the bash shell and this particular script was being run in the bash shell, i issued the command "fuser -k /bin/bash" which seemed to work but the consistent rebirth of this never-dieing processes rendered this command ineffective
mind you, if it wasn't for the fact that the system was getting slower and slower, i probably would have done something smarter but i had to think quicker than the rest of the admins in my team. am the one that messed up here.
i think changing the ownership of the script that started this would have been the best way but "kill -9 -1" wouldn't have hurt to try out.
by the way, how do i use that command?
is it kill -9 -1 (the username) or what?

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
