[FLASH-BUGS] loaddata failure with "Too many open files"

[Leonid Malyshkin]

Hi Mike and Jonathan,

I noticed that loaddata can open the same file as many times as you want 
(>200 times). So, I tried to cheat IDL by copying files with different 
order numbers (in a loop) into a single temporary file. The idea is that
this temporary file has the same id and the same location on disk 
(although has different size and different contents).

Unfortunately, it did not work, neither on SGI no on Linux machine. 
If I do the following:

SPAWN, 'cp rosetta_hdf5_plt_crn_0000 rosetta_hdf5_plt_crn_9999'
b=LOADDATA('rosetta_hdf5_plt_crn_9999','magx')
SPAWN, 'cp rosetta_hdf5_plt_crn_0001 rosetta_hdf5_plt_crn_9999'
b=LOADDATA('rosetta_hdf5_plt_crn_9999','magx')

IDL loads data OK the first time, but gets killed the second time with 
the following message:

On SGI:

Jonathan said the error from my previous email happens only on SGI. 
Therefore, this new error is probably different.

What could it be?

Thanks a lot,
Best wishes,
Leonid
