Description
(CNTR2000
network board responds with a request for data from the file
server that the file server does not have.
The ECB or some other code may be corrupted. Eventually, this
error will abend the server.
If this counter is non-zero, you should try to find the software that
is corrupting the data.
(CNTR2000, NTR2000) This counts bad Adapter Request Blocks
(ARBs).
Normally the network board (adapter) uses one of four known
commands to communicate with the driver.
If a network board sends a command that is not one of the four,
the driver does not recognize the request.
This error is not a catastrophic error.
Sometimes old adapters send bad ARB requests because of
software problems on the board.
NetWare responds to the network board so that the board will not
hang.
(TOKENDMA) This counter tracks the number of times the
adapter had a problem transmitting on the bus.
The adapter interrupt occurred from the firmware on the board.
(TOKENDMA) This counter tracks the number of packets
received that had to use an ECB over 16 MB.
This number should increment only when more than 16 MB of
RAM is used in the server.
(TOKENDMA) This counter is incremented when a DMA transfer
completes with a bus error.
If this counter is incremented, it could indicate a hardware
problem.
