Description Luis Domingos 2003-04-02 02:50:51 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

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):

How reproducible:

Steps to Reproduce:
1.In a windows box do a telnet to linux
2.Run top
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.
