almost the same here, I just happen to have an ASUS PB2DS.

Just tried it here (started 2 of them, while 2 other IDL-Jobs + one
mprime were running) - no problems whatsoever.

unlikely.  You would be able to see that in e.g. top

Hm, maybe a problem with the libraries IDL is linked against!?
Sorry, can't give any more help there...

Try to find out the exact library version IDL was compiled with, and
