[linux-lvm] create more than 30 snapshot s??



Hi!

I am using lvm2 with FC5 right now.
But ,when i create more than 30 snapshots from same
logical volume.
I getting error message.

device-mapper - reload ioctl failed: Cannot allocate
memory


When i searching "Redhat Speaks".

http://www.redhat.com/magazine/009jul05/departments/red_hat_speaks

"In theory, any number of snapshots can be created for
a particular logical volume"

Why i can't create more than 30 snapshots?
How to fix it?
