Hello. I'm running a number of NetBSD-9 and -current as of 99.77 amd/64 domu machines on a couple of different servers with FreeBSD as dom0. I'm getting the following messages from the kernel: xennet0: rx no cluster Much of the time, these messages seem harmless, but occasionally, the network locks up on machines that display this message.
In looking at the source code, I get that this is a pool allocation failure in if_xennet_xenbus.c, but I don't understand which memory resource it's running out of and if there is a way to increase that resource. In general, the domu's in question seem to have plenty of memory and I don't see a lot of memoory pressure for other tasks on the systems. Has anyone else seen these messages on their domu machines and does anyone have ideas on how to correct the issue? -thanks -Brian
