Are you running with the default 512M? If so, you can change it: http://www.unidata.ucar.edu/software/idv/docs/userguide/Faq.html#memory Also, there are a number of things you can do to use less memory: http://www.unidata.ucar.edu/software/idv/docs/userguide/misc/PerformanceTuning.html Or perhaps thre is a memory leak. Were you running and doing things for a long time? -jeff Ticket Details =================== Ticket ID: LCG-240451 Department: Support IDV Priority: Normal Status: Open
