[linux-lvm] device-mapper: Could not create kcopyd client

I'm trying to add a number of simultaneous snapshots of a single origin
and getting the following from the kernel log:
device-mapper: Could not create kcopyd client
device-mapper: error adding target to table
device-mapper: Could not create kcopyd client
device-mapper: error adding target to table
I was able to create 4 then I got:
device-mapper ioctl cmd 9 failed: Cannot allocate memory
Couldn't load device 'vg0-centos4.2--x86_64--boulder--client10'.
Problem reactivating origin centos4.2-x86_64-boulder-pristine
and then another attempt produced:
device-mapper ioctl cmd 6 failed: Invalid argument
Couldn't resume device 'vg0-centos4.2--x86_64--boulder--client10'
Aborting. Failed to activate snapshot exception store. Remove new LV and retry.
This one seems to have created a target though. Not sure if it's
functional or not though.
I am trying to do all of this on Fedora Core 4 with kernel
2.6.15-1.1833_FC4smp.
Any ideas?
