Crash trying to profile memory on large process

Postby Nickwwest » Tue Apr 23, 2013 7:00 pm

I'm attempting to profile the memory of an application that uses around 8GB of memory when running but the application crashes when I attempt to take a snapshot. I'm able to successfully snapshot the application when it uses a smaller dataset (only uses about 400MB). The problem I'm attempting to investigate doesn't manifest itself on a smaller dataset, only on a large dataset.

My dev environment is 64bit with 64GB of RAM so there shouldn't be any hardware limitations.

Is this a known issue? Is there a work-around? Do I need to set some command line switches or something? I'm using ANTS Memory Profiler 7.4.0.40

This just simply won't work- ANTS has a hardcoded limit of 4GB per snapshot.

Ah, OK :(

Any chance this will get fixed in a future version? Apps keeping getting bigger and bigger.
