Hello.
I've been wrestling with this on and off for a few months now.  I have 
an assortment of systems (some Dell Poweredge R515, R610, and IBM 
x3630M3) with 10 gig Myricom ethernet cards acting as nfs servers to 
Linux HPC compute clusters (12-36 nodes, 384 - 480 cores) connected via 
gigabit ethernet.  They are also connected to the outside world via 
onboard bce (Dell) or igb (IBM).  After a variable length of time, I 
will lose all network access to a host. Connecting via console, the 
machine tends to be fully responsive.  A reboot clears the problem, but 
I have yet to figure out any sysctls/loader.conf tunables to clear the 
problem and make it stay away.  PF is in use to restrict access to the 
host to a pair of public /24's, and to 10/8.  If there is a way in zfs's
sharenfs property to make that restriction, I'd be happy to change, but 
I really don't like leaving nfs open to the university's quartet of 
/16's, so PF it is.  The vlan2 interface has mxge0 as its parent.
Thanks for any help.
This host is getting ready to crash soon, based on netstat.

Hi, I vaguely recall some pf issues that caused the state table to not get flushed and things to get stuck. I think it fixed post 10.0-REL. Maybe update to 10-STABLE and see? -a On 2 July 2014 08:11, Bob Healey <healer at rpi.edu> wrote:> Hello. > > I've been wrestling with this on and off for a few months now.

I've been running one of these machines without pf, and it has ceased 
responding on all interfaces (mxge and bce).  The console still works 
fine, and a reboot will clear the problems for now.  I'm running out of 
ideas.
