What happens to parent process, when a child process is created using vfork() and killed before calling exec

2014-10-28 Thread Kevin Peterson
Hi, 

When a process is created using vfork() child process is created and starts 
running in the parent process address space, until exit() or exec() is called. 

What happens to the parent process, if some one kills the child process before 
calling the exit()/exec()?

Thanks,
Kevin Peterson

Is there any way to kill the process which went to uninterruptible sleep (D) state??

2014-02-07 Thread Kevin Peterson
Hi, 

Is there any way to kill the process which went to uninterruptible sleep (D) 
state due of some reason without rebooting machine??

I observed one of the process went to D-state during performance runs. Now, not 
able to kill the process using pkill or kill commands? Finally, we have to 
reboot the Linux machine.

Can anyone helps me out for this situation?? I don't want to reboot the machine.

We can kill the Zombie (Z) process but not able to kill process which is in 
D-state.

Thanks,
Kevin Peterson

Windows exe files are not working in Fedora 18 even after installing WINE?

2013-06-25 Thread Kevin Peterson
Hi, 

I am designing an application for client-server.  Client and Server both 
applications will be hosted on Fedora18. However, for client application, I 
need windows executable, so I installed wine but it’s not working.

Thanks,
Kevin Peterson

How to avoid ARP flux issue in linux?

2013-04-17 Thread Kevin Peterson
Hi, 

I have a setup where eth0 and eth1 interfaces are in same broadcast domain.

But i have a virtual IP configured on eth1 and a physical ip on eth0.
It is observed that if eth0 is default route then eth0 will respond to arp 
request for the IP configured on eth1.

This would cause an issue since traffic will be routed via eth0.

Thanks,
Kevin Peterson
