Replication MQ Sender Is Blocked
The replication queue has reached its maximum size and cannot accept any more data from the
vCenter Operations Manager server.
Problem
The message Replication MQ sender is blocked, data replication has been disabled appears in the
Reason pane of the Alert Summary page for the alert.
Cause
The replication server cannot keep up, either because of a lack of resources or a slow network connection.
Solution
1 Check for possible bottlenecks.
a Increase network capacity.
The most likely cause of a bottleneck is lack of network capacity between the
vCenter Operations Manager server and the replication server.
b If the disk drive on the replication server is slow, replace it with a disk drive that has faster I/O.
c If the replication server CPU is the limiting factor, replace the CPU with a faster processor.
2 Decrease the amount of data that is replicated, either by decreasing the number of resources that are
monitored or increasing the monitoring interval between metric data collection samples.
