bolt k/v pairs are only valid for the life of a transaction. This means the memory that the k/v pair is referencing may be invalid if it is accessed outside of the transaction. This can potentially cause a panic. For reference: https://godoc.org/github.com/boltdb/bolt#hdr-Caveats To fix this issue, unmarshal the stored data into volume meta before closing the transaction.
