Dear AIPS,

I am running an 8192 image with about 300000 visibilities. When IMAGR
(31DEC99) reaches the "minimum clean flux density" message triggered by
FLUX, it fails to stop.  Instead, it starts incrementing the iteration
counter by one at a time.  It also prints the warning message, "CLMPAC:
NOT ENOUGH ROOM FOR ALL MAP POINTS".  The complete message text follows.  
I note that I have been table to cut off IMAGR by communicating a small
value of NITER via the TELL facility.

IMAGR1: Reached minimum algorithm flux = 100.993 MilliJy iter=     2784
IMAGR1: Total Cleaned flux density    =  267.339      Jy     2784 comps
IMAGR1: ALGSUB: Ipol gridded model subtraction, chans    1 through    1
IMAGR1: Field   1 min = -512.8 MilliJy,max =  540.3 MilliJy
IMAGR1: BGC Clean: using  205 cell beam + residuals >    32.92 MilliJy
IMAGR1:    19992 Residual map points loaded
IMAGR1: Reached min. Clean flux density=  79.967 MilliJy iter=     3216
IMAGR1: Total Cleaned flux density    =  270.837      Jy     3216 comps
IMAGR1: ALGSUB: Ipol gridded model subtraction, chans    1 through    1
>IMAGR1: Field   1 min = -504.5 MilliJy,max =  534.5 MilliJy
IMAGR1: BGC Clean: using 1615 cell beam + residuals >   -61.04 MicroJy
IMAGR1: CLMPAC: NOT ENOUGH ROOM FOR ALL MAP POINTS
IMAGR1:      844 Residual map points loaded
IMAGR1: Reached min. Clean flux density=  74.887 MilliJy iter=     3217
IMAGR1: Total Cleaned flux density    =  270.844      Jy     3217 comps
IMAGR1: VISDFT: Begin DFT component subtraction
IMAGR1: I Polarization model processed


I have never seen this before.  Is the AP size too small?
RUN SETPAR shows:
