Whoa! Never set the minimum heap size (-Xms) this high! The virtual machine will try to allocate all the minimum heap size at startup, filling uselessly your memory. On the other hand, you can set the maximum heap size (-Xmx) very high if you want, it will only be used if needed (but I'd recommand not using a value higher than your physical memory, except if you are working on a server environment). Actually you probably don't need to change the minimum heap, memory will be allocated as needed. Setting the minimum heap is useful if you know your program will always use that much memory and you want it quickly allocated at startup. -- Renaud Michel pgp: 0x630E6AC4 (fingerprint: E051 75D0 0E02 4D7B 0384 5D8F 2A70 C289 630E 6AC4) _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
