Ahh. Of course. I should have thought of that.

Hmm. The machine I'm running with has 65535 for [rw]mem_default &
[rw]mem_max. I assume this is a 32 bit value so I could go up to a megabyte
if needed to get the performance consistent on the bound channels. I also
assume I must make the same changes on all affected machines. I'll try some
more tests & get back with the results.
Thanks.
