 Description   
Hey,

currently i'm experiencing replication problems within my cluster (2 server, current version). most of the time the replica item count of my first node is not equal to the active items of the second node. sometimes the problem occurs in both directions. i can't find the reason for this problem. attached some debug informations (73=node1, 75=node2):

http://kliemeck.de/couch/73-all.log
http://kliemeck.de/couch/75-all.log
http://kliemeck.de/couch/73-config.log
http://kliemeck.de/couch/75-config.log
http://kliemeck.de/couch/73-tap.log
http://kliemeck.de/couch/75-tap.log

73:
 vb_active_curr_items: 97
 vb_replica_curr_items: 124

75:
 vb_active_curr_items: 124
 vb_replica_curr_items: 92

-> 5 keys are missing on node 75

h0lng,

Can you run /opt/couchbase/bin/cbcollectinfo and attach the logs that it outputs. It is not possible for me to diagnose this issue with only the information provided here. I also recommend upgrading to Couchbase 2.0.1 since it contains a lot of bug fixes.
