2463.0. "DECBridge 90 - System Buffers" by RDGENG::GREID (Hail,Hail,Hail and Kill!) Tue Jul 04 1995 06:50

    I seem to be seeing several DECbridge 90s with what appear to be large 
    values for the counter "Sys buffer unavail. errors:". Not being able to
    find an explanation for this in the DECBridge90 Manual, are these
    caused by a faulty Bridge or a backplane problem ?
    
    Bridge 1:
    Event counters:
            Sys buffer unavail. errors: 2,193
            WG size exceeded errors: 2,890,525
    
    Bridge 2:
    Event counters:
            Sys buffer unavail. errors: 805
            WG size exceeded errors: 0
    
    Bridge 3:
    Event counters:
            Sys buffer unavail. errors: 166
            WG size exceeded errors: 0
    
    All three Bridges are running DEWGB V2.2 and FPROM V3.1.

    Jean-yves,
    
    	I have 22 DECBridge 90s of which 17 are at firmware version v3.1
    and only five are clean of system buffer errors. The other 12 range
    from a couple of hundred, to four that have massive totals. 
    
    	The worst four list 2193, 4586, 9292 and 22754 for system buffer 
    errors.
    
    	Now these four are all running DEWGB V1.14, but even the ones
    running V2.2 are showing these errors although not as many.
    
    	Giles.

1/ Do you have any errors on the cable where are hooked these bridges

2/ "System Buffer" is a very old symptom,some improvements have been done
    in new Firmware version.started with V3.0 and in a new hardware referenced  
    with ROM V2.X

  i don't know if this information can help you, may be a quick check
  of  Traffic on the wire ( Utilization, errors collisions) will be
   more useful.
