Hi OSF users,
I'm having a problem with a 3000/500 system, OSF/1 v1.3A, 128 MB mem,
and DEFTA-FA FDDI card. First, the system seems extremely sluggish
whenever anything runs over the FDDI. Second, using vmstat, I see
things similar to the following:
Virtual Memory Statistics: (pagesize = 8192)
procs memory pages intr cpu
r w u act free wire fault cow zero react pin pout in sy cs us sy id
2 35 19 13K 251 1443 33 0 33 0 0 0 5 154 52 1 2 98

2 33 19 13K 410 1423 33 0 31 0 2 0 54 157 80 1 7 92
where the free memory drops to quite low. Does anyone know what "wire"
means? I think it was discussed before, but I forgot.
The real mystery is that I have another system identical to it that does
not exhibit the same problem. (It also does not have a lot of FDDI
activity; does that have something to do with it?) I'm going to try to
see if both systems have the same kernel configs (I think they do).
But in the mean time, does anyon have any suggestions as to how I can
start finding out where the cause of the slow down is? (uerf does not
show any errors)
One other symptom: large file transfers over the problem system becomes
slower and slower, and I get the message: "fta0: Ring Initialized" on
the console. The FDDI is connected into a Cisco hub.
thanks in advance for any insights.
