Re: [Hypercontent-users] strange problem after server crash

[<al...@bi...>]

Hi Carl,
The transaction problem is due to a stale lock left over from the crash, which can be removed easily 
from the command line.  

<repositories>:rm -f */workflow-data/*/file.lock

The null pointer makes it look like the system was in the middle of writing a file when the crash 
occured; you may have to identify which file this is and delete and recreate it.  Your best bet for 
finding the culprit is to look for an empty properties file.

<repositories>: find ./ -empty -name file.properties 

If that doesn't work, try

<repositories>: find ./ -empty -name edition.properties 


Cheers,
Alex
