Hi,
I have a module by the name gateway, and it core dumps and gives a cma_dump.log file which says:
%Internal DCE Threads problem (version CMA BL10+), terminating execution.
% Reason: dispatch: no available VP (uniprocessor)
The current thread is 3 (address 0x40107c40)

Am not quite sure as to why this problem occurs, and while trying to debug with dde(which am not familiar with, agn), this is what I see:
