IGV browser memory leak?

Hello,

I am using IGV 2.8.2 for Linux (Ubuntu 18.04 here) to view some bam files. I have a reference bam of 20 Go and other little bams of a few Go each. I changed the -Xmx parameter in the igv.sh script to 50g -Xmx50g

However, I run into "memory is low" warning. Is it normal/ expected that 50 Go of ram is not enough to see a 20 Go bam file + a sample bam of a few Go?

Thanks

igv ram

To view the BAMs you don't need to extend your memory, IGV will look into the BAM and extract the reads for the location you are visualizing.
