I have a machine running 5.4 stable, with 3 em cards:
(1) Two 82543GC with fiber=20
(2) One 82544
All of them are shared irq 11( from vmstat -i)
=20
The problem is:
After the system run about 3 hours, there will be large "Ierrs"
with the em0(BTW, em0 is in promisc mode).
I use "sysctl hw.em0.stats=3D1", found there are a lot of =
"missed
packets" and some "Receive with no buffers".
Em0 is in polling mode, and hz is 2000, burst_max and
each_burst is the default value.
The system is not heavy loaded, incoming rates of em0 is less
than 150Mbits/s. em1 and em2 are not connected.
And pps is less than 30k.
After 3 hours, the ierrs raise quickly every 1 minutes!
From pciconf, I found the driver version is "1.7.35".
=20
I think is a problem with em(4) driver.
Anyone meet such condition?
