OK.

You want to look at System -> General System -> General System
Information. Item 20. MAXPRMEM is the maximum amount of private memory
available to any process. The Linear Memory report shows it, but it's a
bit harder to see.

It is interesting to note that:

SSAVER

is chewing up a lot of address space. It's got:

PMSHELL

beat by a bunch.

There is 21.938M between the private and shared arenas.
Shared arena starts at 04000000, which is 64.000M.
Free memory from 04000000 for 240.000M, which is equivalent to 3840 64K
spaces.

This says you have 320MB of linear address space available in the private
arena assuming nothing gets added to to the shared arena. This should be
plenty.

Well, you knew that. :-)

No, it's the trace commands. See:

http://home.earthlink.net/~steve53/os2diags/TraceRef.txt

Get it up and running using the file open tracepoints. I'll figure out
the memory trace points are later.

Since this is Warp4/FP15, use the MCP/eCS instructions (i.e. os2krnl4).

Also, just in case there's some sort of odd interaction, try shutting down
SSAVER, CCHMAIN and PPM2MON, if you haven't already done so.
