[Condor-users] Errno=14, taking checkpoint doesnot complete

[Tanzima Zerin Islam <tz.islam@xxxxxxxxx>]

Hi, I have an application compiled with condor_compile. I am trying to run it in standalone way using:
./executable input -_condor_D_ALL

then from another shell I am sending checkpoint signal : kill -USR2 pid
But this is what I get:

 This debug message clearly shows some error occurred so I only see mcf.ckpt.tmp being generated.
Any idea what errno=14 means? checkpoint's size might be the reason?
