Hello there!

Perhaps this is a little off-topic, but I notice this only on the Centos 
box.
I'm running Centos 4 on an AMD64 which has the following entries in the 
fstab to connect to NFS shares on a Fedora3 box:
192.168.1.12:/home/angelo/ /home/angelo/NFS_share1 nfs 
rw,addr=192.168.1.12 0 0
192.168.1.12:/home/angelo/data /home/angelo/NFS_share2 nfs 
rw,addr=192.168.1.12 0 0
192.168.1.12:/home/angelo/data2 /home/angelo/NFS_share3 nfs 
rw,addr=192.168.1.12 0 0
I have opened ports 111 (TCP), 648 (TCP), 651 (TCP) and 2049 (TCP and 
UDP) in iptables on the FC3 box and I can connect to them, but after a 
while I seem to loose the connection to the shares.
When I try to move into them while in a console I get the error:
bash: cd: NFS_share1: Input/output error
In Nautilus I don't even see the directories anymore and in 
/var/log/messages I get this error msgs:
Apr 24 20:17:02 solaris kernel: RPC: garbage, exit EIO
There are not entries in the /var/log/messages on the FC3 box.
If I manually umount them and then mount them again, I can use them 
again for a while....
The exports file on the FC3 box looks like this:
[root at imhotep etc]# more exports
/home/angelo             192.168.1.*(rw,sync)
/home/angelo/data        192.168.1.*(rw,sync)
/home/angelo/data2       192.168.1.*(rw,sync)

Anyone any idea what is wrong here?

Thanks in advance,
Angelo
