Hi all,

Can anyone advise how I can resolve this? It appeared out of the blue this morning.  
Is it a bug?

Hey there,

did you maybe have a full disk at any point ? We have seen this issue before if there was an out of disk space error.

You may try to add the following line to the "stardog.properties" file in you home directory:

`storage.wal.recovery.skipCorrupted=true`
