Hi list,
I have a problem with a NFS exports: the client freezes while transfering 
"large amount" of data.

Both client and server are FreeBSD-5.4-RELEASE machines, builded on 
Tuesday, May 10.

Here's some info:

--- SERVER ---

# /etc/exports
/share -maproot=0 -network 192.168.1.0 -mask 255.255.255.248

# relevant lines on /etc/rc.conf
rpcbind_enable="YES"
nfs_server_enable="YES"
nfs_client_enable="YES"
mountd_flags="-r"

# ifconfig rl0
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         options=8<VLAN_MTU>
         inet 192.168.1.6 netmask 0xfffffff8 broadcast 192.168.1.7
         inet6 fe80::20e:e8ff:fe8b:2af8%rl0 prefixlen 64 scopeid 0x2
         ether 00:0e:e8:8b:2a:f8
         media: Ethernet autoselect (100baseTX <full-duplex>)
         status: active


-- CLIENT --

# ifconfig re0
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         options=18<VLAN_MTU,VLAN_HWTAGGING>
         inet 192.168.1.3 netmask 0xfffffff8 broadcast 192.168.1.7
         inet6 fe80::202:3fff:fe67:fc69%re0 prefixlen 64 scopeid 0x2
         ether 00:02:3f:67:fc:69
         media: Ethernet autoselect (none)

# mount srv-file:share /share/
# tar -cvzf /share/home.tar.gz /home

I see the files being added to the archive, after about 8MB (I tried making 
the archive locally to see the size) the client freezes.
I can in no ways kill the tar archiver (killall, kill -9, Ctrl+C don't work)
I can't umount the share.
I have to brutally shut down the computer.

On my share, I see a file name home.tar.gz of size 0 Byte


I can't understand what's happening when the client freezes, any help or 
opinion is appreciated!

Thank you very much, best regards!
