VFS: file-max limit 8192 reached
nfs: server toaster not responding, still trying

Does any know what this is refering to " VFS: file-max limit 8192"? df seems to hang on me. Why? Thanks.

Some process has too many files open. Try this:

$ cat /proc/sys/fs/file-max

You should see some number there. You can change it by echoing a new one in:

$ echo 32768 > /proc/sys/fs/file-max

When the file descriptor index fills up, wierd things start happening.

Hi,
Get BAck with results after trying these things
Can you ping to localhost ?
Can you ping to 127.0.0.1 ?

#ifconfig lo
Does it show 127.0.0.1 255.0.0.0 UP RUNNING ?
If not try this
#ifconfig lo up

Check whether this file exists.
/etc/sysconfig/network-scripts/ifcfg-lo
and check it's contents.
Also check this file
/etc/init.d/network

neighbour table full means that ARP table is full and this is caused because of problems in localhost configuration or bad netmask.
