[CentOS] lvremove killed

hi,

My volume group is vg. Inside that i have around 10 lvm partitions
(each of 100GB).

When I try to remove partitions using

lvremove /dev/vg/lvm1

It acts like the machine freezes and after a long time the lvremove
process gets killed saying "Killed"

Whats wrong here.

I don't see anything interesting in /var/log/message


Thanks
Paras.
