Re: spec Channel Access calls timeout

[Tim Mooney <mooney@aps.anl.gov>]

I talked with Jonathan Lang, and he described two separate problems:

1) Occasionally (maybe a few times per week) Jonathan sees a timeout
message in spec's console window.  He sees the message mostly during
scaler reads, and hasn't seen any consequences other than the message.
Dean Haeffner also has seen this message at roughly the same rate, and
also hasn't seen any other consequences.  Jonathan noticed that the rate
went down when he upgraded the workstation running spec.

2) Less frequently, Jonathan and Felix Krasnicki have gotten spec, or
a motor record that spec is talking to, into a state in which the motor
doesn't respond to repeated messages from spec, and this state persists
until the motor is moved by some other client--usually medm.
