The Revision is a java long type inside jackrabbit. The Max value of a long is 2^36 = 68 719 476 736 If you have 434339 changes on one day the max value will exceed in 158216 days. These are 433 years ... i think you could run jackrabbit a long time.
Of course you can reset the revision. If all cluster members are up to date and stopped you can reset the global revison and the local revisions in the db. But be carefull and better test it before in a test environment... greets claus
