hiya,
I've just upgraded a production Xen to FC5.2200 + the Xen userspace
stuff and its exhibiting some nasty problems. A couple of hours uptime
is followed by all domU networking stopping.
Here's dmesg in dom0:
xen_net: Memory squeeze in netback driver.
printk: 4 messages suppressed.
xen_net: Memory squeeze in netback driver.
printk: 4 messages suppressed.
And xm dmesg:
(XEN) (file=memory.c, line=66) Could not allocate order=0 extent: id=0 memflags=0 (0 of 63)
(XEN) (file=memory.c, line=66) Could not allocate order=0 extent: id=0 memflags=0 (0 of 63)

(XEN) (file=memory.c, line=66) Could not allocate order=0 extent: id=0 memflags=0 (0 of 63)
Googling has shown inconclusive results - a couple of possible fixes but no explanation
why (and no consistent fix.)
Any ideas?
Thanks,
Adrian
