[mat-dev] MAT analyzed a 163GB heap dump successfully

[Josef Lehner <josef1207@xxxxxxxxx>]

Hi MAT team,

As requested in this bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=579427#c0 I want to share with you that we were able to successfully analyze a 163GB heap dump using MAT.

On April 1st (no joke) one of our server nodes was in memory troubles and an automatic heap dump was created:

Heap dump file size: 163 GB (24,5GB compressed with https://facebook.github.io/zstd/)

Heap Dump Overview
Used heap dump: 158,8 GB
Number of objects: 2,041,300,061
Number of classes: 97,510
Number of GC roots: 8,895

Opened & analyzed with the ParseHeapDump.bat running with -Xmx172g.

Thanks again for this great tool. Keep up the good work.

Greetings

Josef
