Darkstar won't start

[Carlos Rafael Ramirez]

Hello,

I have a wonderland server running for weeks, and today people couldn't log in. I decided to restart the dark star server and now it stays in starting up with the message:

I searched and found an unanswered question:

Any advice to fix it without deleting the wonderland folder?

Auto answer: I deleted the berkley database and everything returned to to the las snapshot:

cd wonderland/run/darkstar_server/run/core/data/sgs/dsdb

rm -rf *

Instructions in this page: http://wiki.openwonderland.org/Wiki.jsp?page=Where%20Wonderland%20stores%20things

- the Darkstar database in run/darkstar_server/run/core/data/sgs/dsdb. This is effectively an opaque object storage mechanism used by Darkstar (it uses BerkeleyDB under the covers). The Darkstar database is not a typical database, and cannot be queried or replaced by other database, except switching between the Java and native versions of BerkelyDB. During a cold start -- when you restore a snapshot -- the Darkstar database is removed and a new version is constructed based on WFS. So removing the Darkstar database is a safe operation that will just revert you back to the last snapshot.
