I have a user trying to use the IG Publisher. He's invoking it using -Xmx4096, but actually only getting 247MB available to Java - why doesn't that work? any thoughts?

Is it really -Xmx4096 or do you mean -Xmx4096m? Without the m, you're talking bytes.
Grahame Grieve (Aug 29 2018 at 03:47):
to be precice: -Xmx4096M

Darn. I was hoping this would be an easy one!

did the user try to also specify a minimum size with the -Xms flag? maybe the user has not enough memory on the machine? what kind of java version is it? from jdk8 on you could use jmap -heap <pid> (see https://betsol.com/2017/06/java-memory-management-for-java-virtual-machine-jvm/) to get info about the heap size
Grahame Grieve (Aug 29 2018 at 20:36):
so turns out that the user hadn't specified the -Xms flag in the right place (before the jar, not after)
