I asked this list about a problem I had with FDDI file transfers slowing
down my 3000/500 system running OSF/1 v1.3a. I got a number of responses,
with the general consensus being that the DEFTA-FA of that vintage may
have a firmware bug that causes the ring to re-initialize when used for
file transfers. Also, the fta driver may also have a memory leak problem
which gets worse the more you use it. However, before starting to do
the huge file transfers (rcp), I had been doing huge transfers over
custom socket based programs, and did not have this problem.
However, I am advised that I "REALLY REALLY REALLY" should upgrade to the
newest version of OSF/1 to avoid the above (and other) problems with the
earlier versions of OSF/1. This will have to wait until I solve some
problems I'm having with using CAM to talk to our custom SCSI interface
on any OSF/1 beyond v1.3a; the same set of software run on v2.x or 3.0
causes the system to crash with kernel memory errors.
Thanks to the following for their responses:
