32bits windows JVM (at least from SUN) have problem if you try to allocate more than 1400Mo (with a hard crash of the JVM), on Linux it can go up to 1800Mo. You should'nt have any problem with 64bits JVMs. By the way, reserving all your memory at startup (-Xms1536m) is only useful if you known it will very quickly (like a few seconds after startup) use all that memory, if not it will suck up all your memory and keep it until it need it (maybe never). You should leave the -Xms small (or not set it at all) and only set -Xmx, that way you tell the JVM how much memory it is allowed to use at most and it will take memory as needed. -- Renaud Michel _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
