8 months ago I followed the same steps to test using CRIU3.16, and the results were the same, [root@host1 chkpnt]# cat /etc/redhat-release CentOS Linux release 7.9.2009 (Core) [root@host1 chkpnt]# criu -V Version: 3.16 error log: [Uploading chkpntlog.txt…]()

8 months ago As mentioned before, the CentOS 7 kernel is really old and might be missing some features CRIU needs.

If you try something different please directly try CentOS 9.
Which kernel version fully supports CRIU functionality?
Difficult questions to answer. It depends on the feature you need. It could also be you encounter a situation where CRIU does not support something you need or where CRIU has a bug.
Can we find any suspicion from this log?
Sure:
(00.006550) 98657: Error (criu/eventpoll.c:417): epoll: Can't add event on 0x000006: Operation not permittedThat is your problem. I am not directly familiar with this CRIU feature, but if you prefer CentOS/RHEL distributions then using the latest release of 9 would be a good starting point. If you then still see an error then it is either not implemented or a bug. The problem with CentOS 7 is, that we know that some features are missing from that kernel so it does not make much sense to debug on that kernel.

8 months ago Thanks for your reply, I will use CENTOS 8 &9 to debug CRIU。What is the possible cause of this error?

You still have a problem with eventpoll:

(00.034826) Error (criu/cr-dump.c:1674): Dump eventpoll (pid: 4265) failed with -1Epoll support is sadly not full in CRIU, in your case CRIU can't find target fd of epoll in current process fds, having target fd in another process is not supported (see also https://github.com/checkpoint-restore/criu/issues/1366) having it closed is likely also a problem for current algorithm. I don't see any easy way to fix it except someone diving in current epoll algorithm and supporting all the unsupported cases.
Possible W/A: kill the process (4265) which has an unsupported epoll before migration.
