imcombine memory problem

I'm trying to use the following script to median three images:
where darkin.lis is a text file containing a list of three FITS filenames. It fails with the following error:
DARK_D_196.fits is the first file on the darkin.lis input list. The fits file has 110 header keywords. Having read that the min_lensuserarea variable has to be at least 80 times the number of keywords, I set it to 10000 in the beginning of the script, but this didn't change anything. I also tried a suggestion I found somewhere else in this forum,
The input FITS file size is 2048*2048 pixels*32 bits = 17 MB. Is this too large for imcombine to handle?

set imcombine_maxmemory = 100000000--also no change there.

I solved my own problem by upgrading IRAF to version 2.14 (it was 2.13 before).
