If v21 is not an option, then pls modify your external checkpoint script to keep the task frozen, then look at the contents of /proc/pid/fd and /proc/pid/fdinfo for the checkpointed pid. Something like pid=$1 touch outout /bin/ls /proc/$pid/fd >> outout /bin/ls /proc/$pid/fdinfo >> outout for f in `/bin/ls /proc/$pid/fdinfo`; do echo "/proc/$pid/fdinfo/$f:" >> outout /bin/ls /proc/$pid/fdinfo/$f >> outout done for f in `/bin/ls /proc/$pid/fd`; do echo "/proc/$pid/fd/$f:" >> outout stat /proc/$pid/fd/$f >> outout done Really, I'm assuming that the problem is either an inherited open fd to your pty, or an inherited nscd socket. But let's see. -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
