[Condor-users] standalone checkpointing segmentation fault

[Jason Crane <Jason.Crane@xxxxxxxxxxxxx>]

Hi,

I'm trying to use the condor (6.6.7, dynamic) in 
"standalone" mode to checkpoint jobs.  I have a very simple 
test program that I compiled with condor_compile on both 
Solaris & RH.  During a run I "kill -TSTP pid" the job.  On 
Solaris this works fine producing a *.ckpt file that I can 
use to restart the job using the "-_condor_restart" flag and 
the *.ckpt file.  However, on Linux I get a segmentation 
fault upon kill -TSTP pid, and only a core and *ckpt.tmp 
file are generated.  For what it's worth, if I open the core 
file in a debugger it shows:

Program terminated with signal 11, Segmentation fault.

Thanks in advance for any advice,
