I have a problem :

$ mc vue$master
XIO:  fatal IO error 65535  on X server "HEYDT::0.0"
      after 3451 requests (3347 known processed) with 0 events remaining.

>-SYSTEM-F-PATHLOST, path to network partner node lost

Direct from the VMS System Messages and Recovery Procedures
Reference Manual: Part II:

PATHLOST, path to network partner node lost

    Facility: SYSTEM, VMS System Services

    Explanation: The path to the remote node is lost due to too much network
    activity or communications problems.

    User Action: Wait, then check to see if the node is still reachable.


Unfortunately, I don't think this description goes far enough.  You
should check with the system manager to see if there is some sort of
network problem on your machine.  Typical problems include too much
paging for the NETACP process, too much routing, and hardware
problems on the ethernet devices.

RE: .0, .1

Specifically, "path to network partner lost" means that your end of the DECnet
virtual circuit was expecting a message from the other end, got a timeout,
and exhausted its retry count.  It therefore declared the connection as lost.
However, the underlying DECnet protocol layers still say that the remote node
is reachable.

All sorts of things can cause this problem.  Popular causes include:  remote
system crashed, system in the path between you and the remote system crashed,
hardware link between your node and the remote node suddenly got very busy,
hardware link somewhere between your node and the remote node suddenly got
very noisy or failed entirely.  This isn't an X Windows problem, in any event.
If this problem persists, you should get your system manager and local network
support people involved in tracking it down.

    65535 is a fairly common error message when using small, under-powered
    workstations.
    
    A particularly susceptible combination is a VS2000 with 14 MB which is
    a satellite from a MVII/GPX.  I can get most applications to fail with
    this error just by starting too many applications (say 6-7).

    Yeah, it's kind-of common on 16mb PV0's with SPX's as well.  Any
    X11 workstation is an underpowered workstation.
