Hi,
I was found my memory data on system information (Alfresco 5.2) different with actual server's memory.
If I'm not mistaken, the Maximum Memory (GB) is the heap space memory setting on Tomcat Java setting JAVA_OPTS="-Xms512M -Xmx16g $JAVA_OPTS " (ALFDIR/tomcat/bin/setenv.sh).
My configuration set -Xmx to 16 GB, but it displays 0.97 GB as shown below.

From catalina.out is also show 0.97GB:
catalina.out: 2018-03-28 17:10:16,468 INFO [service.descriptor.DescriptorService] [localhost-startStop-1] Alfresco JVM - v1.8.0_131-b11; maximum heap size 990.750MB
How can I fix this issue?
Since I still got a java heap space issue as discussed here Java heap space issue on Solr4 .
Thanks,
