The Story: Philips in Europe is running large configuration VAX/780s with VMS. (For the record, we here at North American Philips Labs, New York, run 4.1bsd and love it). They have several complaints about VMS such as: >5 edit jobs eats the whole system, the scheduler apparently is very unkind to interactive jobs when the system is running just a few compute bound jobs, dz overhead is very high, etc. The most interesting problem involves rp07 disk drives, and they just journeyed to DEC-land and proved to them on a DEC machine that it does exist (DEC/Europe didn't believe them). The Problem: On a 780 with interleaved memory and one (or more) rp07 disks set for the 2.2 Mbyte/sec transfer rate, with one infinite loop job and one edit job, when the the editor job (EDT) exits and writes out the file, VMS crashes and the directory on the disk is destroyed. With the rp07 set at the 1.3 Mbyte/sec transfer rate, everything is OK. While this sounds like a hardware problem, they wanted me to ask the UNIX world -- The Question: Does anyone have a VAX/UNIX with the same rp07 configuration, and if so, do they have any problems?
