[Neo4j] Re: Can not restart Neo4j after crashed
Recovery is usully quite fast (seconds or minutes). Can you grab a thread dump from when you believe it has hung? My suspicion is something regarding rotation of counts store.

[Neo4j] Re: Can not restart Neo4j after crashed
Well, when I came across the crashing issue, I restart the neo4j, and it blocks at "performing recovery..", and I came back the next morning, and it's still that information. Should I wait much longer for recovery? On Thursday, February 18, 2016 at 3:06:55 AM UTC+8, David Fauth wrote: > > How long did you let 2.2.3 try and recover?

[Neo4j] Re: Can not restart Neo4j after crashed
How long did you let 2.2.3 try and recover? It has to recover the database successfully before it can be loaded into a new database.
