Hi

While scanning the apk, I am getting this error. Due to security issues, I can't share the complete stack trace but some of the error snippets are

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

After this, I even tried node /usr/lib/node_modules/dexcalibur/dexcalibur.js --max-old-space-size=8192, but still no luck.

Please do let me know if I am doing anything wrong.

Also, this is running inside docker but I am getting similar error if I install dexcalibur in VM as well.

Have you tried: [node --max-old-space-size=8192 /usr/lib/node_modules/dexcalibur/dexcalibur.js]

I'm using Windows 10 now, but strangely the heap size does not increased when the --max-old-space-size option used at the back of the location of the javascript file.

I suggests you to check whether [Mark-sweep 2040.1 (2057.5) -> 2038.1 (2058.0) MB] is increased to 8192MB when you tried [node /usr/lib/node_modules/dexcalibur/dexcalibur.js --max-old-space-size=8192]
