Hi,
1)
We recently installed 100Mb adapters in our alphaservers 2100 and connected
it to a Cisco switch. Since then, some messages appear at the console, coing
from the kernel:
vmunix: tu0: FIFO buffer underflow. Data thresold raised to: xxx bytes
Where xxx is 256, 512 or even 1024. What it this ? does it hurt ? How can I
fix it ?
2)
One of our servers is configured as an NFS _client_ to a Novell Netware 4.11
server running Netware NFS 2.1
Sometimes, when a user copies a file to the nfs mount point, he gets a
message like:
cp: i/o error
After that, he retries the cp command and everything works fine. We will
have to automate some file transfers and I don't like that kind of errors.
What is the cause and how could I possibly fix it.
3) Bonus questions
I don't want to bother you everytime a message comes from the kernel, for
example, see question 1. What am I supposed to do when a message comming
from vmunix shows up on the console ?
Is there a manual explaining the meaning of such messages and a way top fix it ?
TIA!
