> 2 Nodes in the cluster both on the same machine, (seperate JVM's)
> All persistance managers using the same MySQL DB,
> Then I connect a webDAV client to one node and upload about 300Mb of data, which all works perfectly on the node I am connected to.
> On the other node in the cluster I see a lot of the following tracebacks. The Revisions are not in sequence indicateing that most are Ok, and the tracebacks continue untill all activity (including indexing has finished)
> ERROR: Unable to read revision '48'. (2007-05-13 09:27:24,209 ClusterNode-localhost1_org.apache.jackrabbit.core.cluster.ClusterNode)

> Looking at the Code in that area, the for loop exists on a null char '\0'. It might be possible that the MySQL driver or table setup is truncating null chars giving rise to the errors.
> The idle node that is creating the errors otherwise looks perfect and the content appears on the idle node within a second or so of being uploaded on the active node.
> (I am uploading using a webDav mount in OSX Finder)
> I will try with the FileJournal just to check that its not a MySQL or JDBC driver issue.
