To answer your question, if you want to configure the memory usage in the broker, it can be re-read but only at broker start time. The log4jproperties *can *be re-read on-the-fly (without broker restart), but not the system-usage etc. configuration.
But there is a hard jvm limit that you have to work within anyway. Once you start the jvm, the -Xmx (for hotspot) value for maximum heap space is set for the life of that vm. Everything that will be on the heap has to come out of that budget (I mean you could only adjust within the -Xmx total in any case.) HTH, Mick Hayes. ----- Michael Hayes B.Sc. (NUI), M.Sc.
