Currently criu dump may hang indefinitely. E.g. in wait for task that blocked in vfork() or task could be in D state for some other reason. This patch adds time limit on collecting tasks during the dump operation. If collecting processes takes too long, the dump process will be terminated. Timeout is 5 seconds by default, but it could be changed via parameter. Signed-off-by: Andrey Ryabinin <aryabinin@virtuozzo.com> Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
