Problem with JAVA memory

Hi, 

I`m in with a problem with JAVA memory in my openfire server. The memory stay with default value, 247,5MB.

I've made the adjusts in the openfired.vmoptions and openfire-service.vmoptions (service mode) but the settings aren't apply.

both are configured with values:

-Xms512m

-Xmx1024m

SO: Windows Server 2008 Standard R2, database openfire default, openfire 3.8.2
