<div dir="ltr"><div>I apologize if this is the wrong place for this question - criu looked frankly like a dev mailing list to me but I don't know where else to post it.<br><br>I wanted to checkpoint (dump) a process and restore it later (presumably
after a reboot) and discovered that this functionality was added with
the checkpoint-restore tools in the crtools package which is presented
as a single utility.<br>
<br>
I tried<br>
crtools dump -t 3916<br>
Error (ptrace.c:75): Unseizeable non-zombie 3916 found, state S<br>
and assumed the user needed permissions I didn't have. Then I tried<br>
<br>
sudo crtools dump -t 3916<br>
Can't open self pagemapError (parasite-syscall.c:257): Parasite exited with 1<br>
Error (parasite-syscall.c:577): Dumping pages failed with 1<br>
Error (cr-dump.c:1506): Can't dump pages (pid: 3916) with parasite<br>
<br>
Has anyone succeeded in getting this to work? (Running ubuntu 14.04)
