Hi!
My much-used AIPS proc SRCS is stopping at the same point in a run with the same messages, and I can’t figure it out although I’ve tried hard.
The proc images and feature-finds 50 channels in an initial 10-sec time range with no problem and writes some SAD output, then gets a few channels into a second time range and stops (with error. messages further below)  I have gone back and run CLRSTAT and ZAP on resulting files and tried re-running, but it still stops.  I have checked to make sure that no other jobs are reading the same UV file, and none are.  
Can you suggest what might be the problem?  Thanks!
 Bob Gray
