[Dmtcp-forum] Killing node causes major problems

[<Dar...@gm...>]

I just installed DMTCP for the first time and am evaluating it. I'm using  
version 1.2.1-1 X86_64 on Ubuntu 10.10.

As a trial, I ran "dmtcp_coordinator" in one window and then in another  
window ran "dmtcp_checkpoint vi asdf" and typed some data into it. I then  
went back to the coordinator window and pressed "c" to checkpoint, and then  
pressed "k" to kill the vi session (I intended that I would load the vi  
state from the checkpoint).

However, at this point things went screwy. The vi window displayed the  
following:

WARNING at kernelbufferdrainer.cpp:100 in onTimeoutInterval;  
REASON='JWARNING(false) failed Message: Still draining socket... perhaps  
remote host is not running under DMTCP

and repeated this periodically. After doing this I became unable to launch  
any new processes from Gnome, and when I tried to start vi from an existing  
terminal it sat for several seconds and then gave an unusual error message.

I rebooted and everything was back to normal. I didn't not try logging off  
and back on -- perhaps that would have fixed it as well.

After I rebooted I tried the same steps again and it failed in the same way  
again, prompting me to reboot. So its reproducible. Does anyone know what  
is going on? Thanks,

Nick
