Dear IDV User, Thanks for reporting this problem. It is indeed a bug related to systems with low memory. (It has nothing to do with 32 vs 64 bit architecture, I think.) Please try the latest nightly build tomorrow, and let us know if the problem is still present. Note the IDV requires at least 512MB. -Unidata IDV Support > Hello - > > We have tried to download the most recent IDV nightly, as well as > Version 3.0b1 on our Linux-32bit machine.
