> From BrokerService, line 711-2:
> systemUsage.getTempUsage().setLimit(1024 * 1024 * 1024 * 100); // 10 Gb
> systemUsage.getStoreUsage().setLimit(1024 * 1024 * 1024 * 100); // 100 GB
> The expression 1024 * 1024 * 1024 * 100 overflows int, so the above lines actually correspond
to setLimit(0).
> Easy fix is to make one of the multipliers a long, for example:
> 1024L * 1024 * 1024 * 100
> Other places may have the same problem, but I did not look for all places.
