Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have a small database that was working fine just a day ago, but now, when I try to start it, the console claims that it succeeds in opening, but the web server hangs.

lsof -i | grep 7474

states that neo4j is listening to the port, and "close_wait"-ing, which I'm told means that the server side shut it down.

The only new error I get is that logback.groovy is missing, along with logback-test.xml, which is very odd, because I set logging to false in the neo4j config file. Here's the output when I start neo4j:

Go to http://localhost:7475/webadmin/ for administration interface.

I thought that this was a problem with the path, so I appended NEO4J_HOME to the neo4j file, like here: https://groups.google.com/forum/#!msg/neo4j/NMVHoflUrHo/warnQUInGCgJ (Bhargava's solution).

Nonetheless, the problem persists. Thoughts? I have no idea what the log files do and why they are needed.

Anyone? Really, even apointer to an explanation might be useful.
