Hi,
Thank you for the assistance. Which parameters do you suggest changing?
TSO/flow control off?
Yep, anything.
Ok, "ethtool -K eth0 rx off tx off sg off tso off" should have turned it
all off.
iptables -L -v just shows 2 rules per Virtual Machine for accounting. This
averages about 100 rules in the FORWARD chain. Example:
Do you know if the problem starts appearing after a certain number of
hosts?
No... I have some servers that are running just 2.6.16-xen (no bugfix
patches) for 30 days without a problem, some of these have rulesets
larger than the ones that crash daily. I'd estimate this affects 90% of
my servers, just some reboot daily and others can make it to 7-10 days.
Thanks,
Matt
