[j-nsp] JunOS on EX-4200 stack corruption

[TiM]

Has anyone seen an issues where, once a stack looses power (all at once,
sadly), some members of the stack come up with corrupt JunOS on them?

We have a stack of 6 EX4200's.  Due to a power issue, all 6 lost power at
the same time.  When power was restored, the Master, the Backup and one
linecard mode switch came up fine.  The 3 other linecard mode switches
didn't.  On powerup they all reported shared libaries not being found and
similar "file not found" type errors.

Reinstalling JunOS from the boot prompt has fixed the problem.

Has anyone else encountered corrupt JunOS problems on EX4200's,
specifically in a stack configuration, before?

Thanks!

Tim
