Yes -- you can set the max heap size by giving "-Xmx4096m" as an argument to the java command that you use to start kepler.  Set whatever  maximum heap size you need, but also note that this may limit some memory-intensive actors from working properly.  I presume that you are using a shell script to start Kepler, so its a simple addition to that script.

Note that we have found some memory leaks with the released version of Kepler, and that those are being fixed over the next couple of releases.  I believe that some of the most pressing memory issues will be fixed in the upcoming release, and that others will be folded in over time. Others on this list may be able to provide more details about these issues and the timeline for memory fixes.

Hi,

I am currently using Kepler 2.0 and it looks like my Kepler got killed when I tried to launch it on a cluster machine. The system policy limits one process to 4GB memory and Kepler consumed 8 GB. Is there any way that we can reduce the Kepler memory consumption? Thanks!

Gary
