Samba 3.4 on FreeBSD 8-STABLE branch.
After a few days I start getting weird errors and windows PC's can't
access the samba share, have trouble accessing files, etc, and samba
becomes totally unusable.
Restarting samba doesn't fix it – only a reboot does.
Accessing files on the ZFS pool locally is fine. Other services (like
dhcpd, openldap server) on the box continue to work fine. Only samba
dies and by dies I mean it can no longer service clients and windows
brings up bizarre errors. Windows can access our other samba servers (on
linux, etc) just fine.

The code in lib/util_sock.c, around line 902:

int open_socket_in(int type,

sock = *psock;

}
#endif

dbgtext( "%s\n", strerror( errno ) );
}
In other words, it looks like something in the kernel is exhausted
(what?). I don’t know if tuning is required, or this is some kind of
bug?
/boot/loader.conf:
mvs_load="YES"
zfs_load="YES"
vm.kmem_size="20G"
#vfs.zfs.arc_min="512M"
#vfs.zfs.arc_max="1536M"
vfs.zfs.arc_min="512M"
vfs.zfs.arc_max="3072M"
I’ve played with a few sysctl settings (found these recommendations
online, but they make no difference)
/etc/sysctl.conf:
kern.ipc.maxsockbuf=2097152
net.inet.tcp.sendspace=262144
net.inet.tcp.recvspace=262144
net.inet.tcp.mssdflt=1452
net.inet.udp.recvspace=65535
net.inet.udp.maxdgram=65535
net.local.stream.recvspace=65535
net.local.stream.sendspace=65535
Any ideas on what could possibly be going wrong?
Any help would be greatly appreciated!
Thanks,
Martin
