[daip] maxpixels loaded to ap

I'm running aips tst on alfirk.  Today I have
been running some imagrs.  Works fine if I
use dotv and set a box.  But if I leave it without
boxes it does the gridding, fits the beam, and then
gives the following message

alfirk> IMAGR3: WARNING: > MAXPIXELS LOADED TO AP!!
alfirk> IMAGR3: ZABORS: signal 11 received
alfirk> IMAGR3: ABORT!

data set is 262724 vis, 1 freq, 2 IF.  

This didn't seem like it was happening a few days (week ?)
ago.  Inputs to imagr follow.
