Hi,
I am using a PB4.1 CEPC image build on a 64Meg Pentium PC104 board.
It seems coincidental that the problem has started since I stated using a
software library package that makes extensive use of "LocalAlloc( LPTR,
nbytes )" and "LocalFree( p )." I find this an odd coincidence since
several drivers use these memory manipulation calls as well so this may be a
moot observation.

The symptom is that after some indeterminant length of time
(minutes/hours/days) I will subsequently get error messages when trying to
start new applications:

"Cannot execute 'cmd'. A critical component is either missing or failing to
start due to low memory."

Applications that are running during this state continue to function with no
perceived problems.

This is less than helpful since sometimes I can get the system information
dialog box to display while the machine is in this state. It indicates
there is about 25Meg of application memory available and about 20Meg of data
memory available. So I don't think the total available memory is an issue.

I am not familiar with the internals of the CE4.1 memory management. Is it
possible the memory has become too fragmented to allow a new application to
execute? ( A wild guess. )

Any idea as to the cuase of this issue or a possible solution.
