dotMemory Snapshot Fails When Private Bytes > ~25GB

I have relocated the core temp and working directory to a drive with plenty of space as previously it was failing while taking the snapshot, now I continually have issues while it tries to process the snapshot.  It appears to be running out of memory which is unfortunate since I need the snapshot from a machine that is low on memory to see where the issue lies.  Furthermore I do not see the capability to take a snapshot/analyze a dump file so I cannot do it offline either (and remote options are limited being in a production data center).

One issue was the entire app hung, other was it stopped having lost CLR4 profiler connectivity and a few other seemingly random issues.  Is this a fundamental limitation or am I missing something that would allow me to perform this type of snapshot?
