Hello, I am having a problem on a Compaq Proliant 4500 with its integrated SCSI controller where on average once per month the machine will be unable to access any SCSI devices (like the system disk :), and the console will display the following message: ncr0: queue is empty I have seen this mentioned a few times in the list, but havn't seen any logical reason or resolution. The only thing out of the ordinary at all is that there is a Compaq 35/70 DLT in a rack chassis. These are supposed to be self terminating ... This tape drive is on the second integrated Compaq SCSI controller. Could a problem on that bus affect the proper operation of the first? (at least as far as the OS/ncr-driver is concerned).
