When using Dubbo to register services to Zookeeper, an exception occurred in the Zookeeper logs indicating that the data packet size was too large.

Dubbo should normally register services to Zookeeper, and the size of the data packets sent should be within a reasonable range (usually not exceeding 1MB).

However, Dubbo is sending exceptionally large data packets (over 1GB), which causes Zookeeper to fail to process them and results in service registration failure.

Dubbo version: 3.3.0

Steps to reproduce this issue
