Why is imaging quick sometimes and slloooow others?

I have 6 sources, each with 2-3 hours of continuum L-band data on them. For five of them, imaging and self-calibration are really quite quick, but one of the sources takes a factor of 5-6 longer to image/calibrate than the others! Its correlator setup is not different, it was taken only one day previous to the other sources, and it has a similar amount of time on source. Any ideas about why imagr seems to choke for this source? Thanks!

Does IMAGR give any helpful messages at the beginning on what it's doing? That might work to isolate where it's so slow.
