803.0. "Child/decterms/cluster transitions" by 43339::BAILEY (Clock Running, 1 Days Left) Thu May 18 1989 14:34

We are running DECwindows on our 20 node cluster with two
'big' machines  (a 6320 and a 8820) acting as servers...


the problem is that if I have CHILD created decterms on both
of the above  _and_ a cluster transition happens  (Clu trans are
very fast.. all (4) big machines have votes with none for the
Gpx's.)   all the DECterms on the 8820 disappear... the decterms
on the 6320 are not affected.. this is very repeatable

Why?   it must be some difference in the sysgen parameters
for the two machines.. but which sysgen parameters???

Come on now, folks.  Someone out there must have come across this friendly 
little feature!

803.2Not cluster related, look at networkCVG::PETTENGILLmulpTue Jun 13 1989 12:567
Which nodes are routers?  Are the network virtual circuits closing due to
Ethernet port resets?  What kinds of Ethernet adapters are you using and
what revs?  What version is the software?

You might look into the currently unsupported TCP/IP transport; it seems to be
less sensitive to this kind of problem.

    I've just look at the nodes in question and the 8820 is routing but the
    6320 is not. This could be it.
    
    We're running DECnet-VAX V5.0, VMS V5.1
    
    I can tell you the rest of the stuff tomorrow when the system manager
    comes in.
    
    
    Thanks,
