Frederico, you're running restore on the live systems without use any of
namespaces, for sure without them there is no reliable way to guarantee
the PIDs match on restore. Have you been considering running your application
in own at lest PID namespace? (take a look on unshare(1) manual). Just
found that Pavel already mentioned this concern in email earlier.
