    I suggested 2.95.3 for a reason - see the aips web page:
             http://www.aoc.nrao.edu/aips
the 2.96 compiler produces code that does not work properly, including
TVFLG and IMAGR among others.

The message below is from a spectral-line clean and stop cleaning
means to stop cleaning this channel and go on to the next.

Use TELL to tell the program to quit at this point.

The MAXPIXELS message is a symptom of the bad compiler producing bad
code.  Your system manager should be aware of the controvery
surrounding 2.96 (not a released GNU version but a stolen in-testing
development copy).  The 3.0.1-3.0.4 compilers also are not recommended
and I have yet to try 3.1.
