[mod.computers.vax] Problem with DECnet between VAX and DEC20.

art@MITRE.ARPA.UUCP (02/12/87)

It is a known problem.  DEC has a patch for it.  They broke (accidentally)
DECnet VAX to all DECnet phase II systems.  We had similar problem to IAS
and they provided a patch.  At same time mentioned that the problem also
occurred on DEC 20's.

    We are experiencing a problem with DECnet between a DEC 20 running
    TOPS20 5.1(6101) and a VAX 750 running VMS 4.4, linked by DMC/DMR. We
    run an application on the VAX which copies files from the 20 using RMS
    from MACRO. This ran OK under VMS 4.2, but with 4.4 the RMS $OPEN fails
    with "RMS-F-SYS, QIO system service request failed" coupled with
    "SYSTEM-F-LINKABORT, network partner aborted logical link". It doesn't
    fail on every file, nor necessarily twice on the same file, but it
    fails a lot. Considered opinion is that it is a timing problem,
    but where we go from there I don't know.
 
    Has anyone out there had a similar problem, and if so have you fixed
    it? Any help or suggestions would be appreciated.
