XDMP-XDQPMAX

Message Text

Too many XDQP listeners on host variable1

Cause

The maximum number of hosts connecting to this host through XDQP has been exceeded. No more than 255 other hosts may connect to this host through XDQP. Hosts in local clusters connect to every other host in the cluster. Hosts in foreign clusters connect to hosts with replica forests. Hosts in foreign clusters also connect through bootstrap hosts.

Response

Avoid creating large single clusters of hosts. Instead use super-clusters and super-databases. For example, 1024 hosts can be organized into 32 clusters of 32 hosts. See the MarkLogic Administrators Guide Chapter about Super Databases and Clusters.
