This is caused by the JVM requiring shared mmap, when the java app does not even need it and the current KM for OrangeFS does not support shared MMAP. We have talked about implementing it, but that would take a while, we also have discussed just putting in a fake out flag for the KM. Do you know if the java app you are trying to use actually uses shared mmap or not? (if not we can look at turning around the fake out flag pretty quickly). This is not limited to JVM , some other apps do the same thing (very very few actually use shared mmap).
There is also this older java bug report (requesting the JVM not do this), its here: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7085890 thanks, -boyd On Tue, May 14, 2013 at 12:30 PM, Scott Roberts <[email protected]> wrote: > Good afternoon, > > Has anyone encountered issues executing applications directly from an > OrangeFS mount?
