Grid Control Loader Trhoughput Critical Error

GC 10.2.0.4

On the home page, I received critical error like this:

Metric Loader Throughput (rows per second)
Loader Name xxxxxxxxxxxxxxxxxxxx:4889_Management_Service,XMLLoader0
Severity Critical

Solution:

Add the following line into the file emoms.properties inside OMS_HOME/sysman/config:
em.loader.threadPoolSize = 2
Don't forget to shutdown oms before any update.
