that box has 2GB ram. and before lvm process is killed, top shows
top - 11:27:24 up 10 min, 4 users, load average: 0.99, 0.71, 0.34

Cpu(s): 18.7% us, 5.9% sy, 0.0% ni, 67.3% id, 8.0% wa, 0.0% hi,
0.0% si
Mem: 2055388k total, 2041136k used, 14252k free, 192k buffers

4550 root 18 0 1927m 1.9g 48m D 94.9 95.6 5:00.00 lvm
if that is kernel memory, why lvm shows a RES of 1.9GB?
