Proc32 memory increase

Hi there,

I have a question regarding the Proc32 process. I found that the memory
usage of Proc 32 is increased after I run my program. So I wonder is it
normal that the proc32 will use more memory or is because that my program
didn’t release resource completely. By the way, under what kind of
situation, the Proc32 will use more memroy?

Thanks in advance!

I can happen if you have vc.
For example if you have program that does qnx_name_locate multiple time
without doing qnx_vc_detach.

Proc32 can dynamically allocate memory for a number of different internal
tables. The most common is page table entries.

Also, any shared memory that is created will have its RAM usage attributed
to (owned by) Proc32, so if you create any shared memory, the nominal memory
useage of Proc32 will grow by the size of the shared memory area, though
Proc32 isn’t actually using up any more memory.

That will burn process table entries – and often result in running
out of resources, but I had thought the vc buffer was allocated in
Net’s space, not Proc32’s.

More likely is shared memory – it is attributed to Proc32.
