Description of problem:
If we have the command top running in one tcp/ip session, for instance putty or
windows telnet,and if we close the window, the process loose the tty and starts
consuming a lots of CPU and put the processor down.These kind of behaviour is
also seen with other programs, like for instance rmcobol.
I discovered that the problem is related with ksh (pdksh), if the user's shell
is bash, I don't have these problems.
This is a issue related with abnormal program termination.
The version of pdksh is pdksh-5.2.14-13.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.In a windows box do a telnet to linux
3.Close the window
4.wait 5 minutes and telnet to linux
5. do a ps -ef | grep top, and you will see top consuming the CPU
Expected Results: 1. The process top should no exists.
