Can anyone tell me what is the maximum size limit of the Virtual Memory in
QNX 4.25? Is it 4GB?

I believe it’s 4GB per process.

Proc, at least used to, have an internal limit due to the maximum
page-table-size it could use.

I’m not sure if that has gone away or not. (Some such limitations
have been fixed, others haven’t.)
