Problems with /var/lib/sss/mc/passwd

[Radim Vansa]

Hello Jack,

the proper venue could be the Foojay.io forums [1] (yes, only recently 
created) or #crac channel on Foojay slack, but this list will do :)

Can you try running the checkpoint with 
`-XX:CRaCIgnoredFileDescriptors=/var/lib/sss/mc/passwd` ? This should 
bypass the checks, though problems may arise on restore if this file 
changes when the application is in checkpoint.
