What causes this issue?

This monitoring tree element (MTE) provides information on the
performance of the enqueue client in SAP application servers. This
client is responsible for routing requests to the enqueue service in
application servers other than the one that offers the enqueue service.
(Work processes access the enqueue service directly in the application
server that offers this service.)
The enqueue service lets applications lock data for exclusive use.
Locking data while it is being used prevents changes to the data in
parallel, which would result in inconsistencies in the data.
