Re: [Neo4j] java.io.IOException when starting REST server on Ubuntu 10.04 32 bit
Hi Todd, We would really appreciate it if you could file a ticket on https://trac.neo4j.org with all the info you can provide. Also, if you have the time, you are definitely encouraged to have a look at the source and submit a suggested patch. (see http://wiki.neo4j.org/content/About_Contributor_License_Agreement for more info) We are super busy right now, but we have not lost track of this. My suggestion is to take it as far as you can on your own first, put all the info in the ticket, and then we can look at it. Thank you.

Todd, Size of the memory mapped log buffer is final and size is set to 1024 * 1024 * 2 bytes (see MemoryMappedLogBuffer). What JVM version are you running? -Johan On Tue, Aug 24, 2010 at 11:23 AM, David Montag david.mon...@neotechnology.com wrote: Hi Todd, We would really appreciate it if you could file a ticket on https://trac.neo4j.org with all the info you can provide.

Re: [Neo4j] java.io.IOException when starting REST server on Ubuntu 10.04 32 bit
Hi David, I've filed a bug report. I'm afraid I've gone about as far as I can in understanding what the problem is and/or how to fix it without just guessing that reducing the memory sizes could fix it, but don't know if that would create side effects. Thanks, Todd ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

Hi Johan, Output of java -version shows: java version 1.6.0_18 OpenJDK Runtime Environment (IcedTea6 1.8.1) (6b18-1.8.1-0ubuntu1) OpenJDK Client VM (build 16.0-b13, mixed mode, sharing) Is that what you are looking for? I've also added this information to the trac ticket. Todd ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
