[GeoNetwork-users] Why does GeoNetwork/Java use so much memory [SEC=UNCLASSIFIED]

[<joh...@os...>]

Hi All,

With many thanks to Simon Pigot, I have GeoNetwork 2.7? set up on our server. A 'ps -ef' command shows that has been started using the following parameters:

/usr/bin/java -Djava.awt.headless=true -Xms2g -Xmx8g -XX:MaxPermSize=128m -server -Dasdd-prod -Dmime-mappings=.. Etc. etc.

It looks like 8Gigs of memory are allocated to run GeoNetwork. When I do a "top" on the server after starting GN I get the following line:

 3893 www-data  20   0 8824m 1.2g  13m S    0 14.7   3:54.59 java

This tells me that GN is using the full 8Gig of memory.

Can anyone tell me why does GN need so much memory? It doesn't allow much memory for other services running on the same server.

Thanks.
