Lots of "swapper: page allocation failure" and other memory related messages - 2.6.16-xen0
(please keep me on Cc when replying)
I have a server running Xen that regularly spews the following.
The box seems to survive fine regardless - just thought I''d let everyone know.

Problem with MTU > 1500, ifconfig segmentation fault
Hi all,
I am using Xen 2.0.7. I have Broadcom NetXtreme BCM5704 Gigabit Ethernet
(rev 02) cards which support frames greater than 1500.
However when I boot into Xen and try to set the MTU to anything higher
than 1500 (e.g., 4000, 8000 etc) I get a segmentation fault. After this
fault, every command fails with a segmentation fault. I saw a similar
bug report posted here:

network_alloc_rx_buffers panic
Some users are hitting this panic in network_alloc_rx_buffers()
when running a big network intensive app:
/* Check return status of HYPERVISOR_dom_mem_op(). */
if ( rx_mcl[nr_pfns].args[5] != nr_pfns )
panic("Unable to reduce memory reservation\n");
I''m not clear on what is happening here. Are the domains changing size?
Which memory reservation is being
