This would be a kernel parameter. Errno=12 is ENOSPC - Not enough space. You might just be running out of memory. I usually set up a machine with swap = 2Xmemory but for an SMP box you will need even more. Try increasing swap space to 256MB or even better 384 or 512 MB, or just get a 1GB disk (cost about $120) and make that entire drive the swap disk. Art S. Kagel
