It is indeed advised to use sunjdk as openjdk is a bit behind as far as bug fixes are concerned. Moreover, 0.6.3 is pretty old now and we do have fixed a number of issue related to load spikes, so before investigating further the best advice I can give you is to upgrade (either to 0.6.13 if you really feel like staying on 0.6, or to 0.7.5). -- Sylvain
