Actually, it is limited by NMBCLUSTERS = (512 + MAXUSERS * 16) in conf/param.c 2.2-ALPHA works better, which NMBCLUSTERS can be (512 + 18 * 16) On same motherboard, the limit can be changed when the CPU clock changes. For example, on Intel PT-2000 motherboard, if CPU clock is 100 MHz, the limit of the maxusers for NMBCLUSTERS could vary from 0, 3 - 15 (some Motherboard does not work at all). Changing CPU clock up to 120 MHz, the limit will stay at 15. (2.2-SNAPs) I thought that might be caused by page boundary, but it doesn't look like according to the behaves above. I will keep to track down the problem further. In the meantime, if any one has some idea what could cause this kind of problems, please let me know. Thanks, -Jin
