Hi,
With a new Kernel and some tweaks (PREEMPTION) disabled I can let
our 2CPU IBM server running about one hour, and then I get:
ping: sendto: No buffer space available
and the box disappears from net ...
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
inet 157.161.9.17 netmask 0xffffff00 broadcast 157.161.9.255

media: Ethernet autoselect (100baseTX <full-duplex>)

After a few tests I found out that our network guy has set up some IPv6
entries in the dns. And of course they were used by milter-connects ..
After reverting everything back to IPv4, the "No buffer space available"
seems to be gone.
Maybe this is related to some other problem with this driver, (IPSEC etc).
Martin
