MDM Trouble Report for 2006 Oct 8

Telescope: 1.3m
Observer(s): Martini, Atlee, Bird, and Lacki (Ohio State)
Instrument: Echelle

Problem(s) Encountered:
We have encountered the following error message while using 
CCDCOM to control echelle at the 1.3m:

Clearing the CCD.... Done, cleared CCD 1 time
Getting TCS/MIS info...done
Exposure Started, Ctrl+C to pause
Exposure Complete, Elapsed Time = 5.00 sec
Beginning CCD read of 2080 by 2048 (4259840 pixels)...
ccd_aread: wrong aio finished; expected 1.  This is bad.
*** Error encountered in asynchronous read: data suspect
Failed, return code = 1474560, elapsed = 44.639000

this failure has been slowly increasing in frequency; last 
night we saw it twice the whole night, at the beginning of 
tonight we saw it about once per hour, now we see it several 
times per hour. We have tried the following: 

1) typed  df echelle  then  util init  

2) restarted CCDCOM

3) performed a cold reset

Each of these appeared to help, if briefly, although this 
is difficult to say with certainty. Also, the error message
appears more common if we are writing another file to disk 
at the same time (e.g. running an IRAF task), although 
we have also seen it when nothing else is running on the 
computer.
