Indeed. Always pair an ABITRARYFUNCTION_OPEN with an
ARBITRARYFUNCTION_CLOSE...or a free lun in the case of openw, openr,
etc...

Thanks for your response. I had actually tried EOS_SW_ CLOSE already,
but your post helped me realise that the problem was most likely due
to memory. In the end, I used HDF_SD_END, sd_id which seemed to solve
the problem!!!

You're probably not closing your EOS_SW id each time you go through
and hit the physical limit for IDs to generate. So you need to
include an EOS_SW_CLOSE piece somewhere in your code to make sure
you're not just generating new ids without closing them. Same idea as
for all files...don't open it unless you're willing to close it prior
to your next 29 openings. Hope this helps.
