There are just a few variables covered by ENABLE_THREAD_SAFETY. I wonder
how the program manages to spend so much time allocating memory to eat
all of it. Could you give us some more info about your source code? Do
you use descriptors? Auto allocating?

Hi Michael,
Not exactly sure what you are asking about - descriptors and auto
allocating.
The program processes about 800000 packets a day, which can update
several tables.
It runs continously reading udp packets from systems at remote
locations coming in over the internet.
It has a global
exec sql include sqlca;
then a number of functions that get called with each function having
it own
xxx( args,... )
{
EXEC SQL BEGIN DECLARE SECTION;
a bunch of variable
EXEC SQL END DECLARE SECTION;
with various EXEC SQL inserts, updates and selects.
with checks of sqlca.sqlcode to determine if the sql statement succeeded.
}
Steve
