You could be seeing a loop of some type. I've seen this in the 4ge world
every now and then. Of course, I guess that it is possible for a program to
be actually doing some work . . .

Hallo everyone, I have something that's been a problem to me for quite some
time now. If I run a "top" on HP, showing me the processes using the most
cpu power, I often find 4gi's sitting right on top, using 60 - 90 % cpu
power.
I also think these programs are not doing any selects (as seen from the
current sql statement from onstat -g ses), but something else. How can I
find out what the program is doing, and why it is using so much cpu power ?
One example I have this morning:
onstat -u | grep 15373
c000000094be4828 Y--P--- 15373 izakb tPe c000000088e55d80 0 163 0
Flags are normal. If I get the current sql statement using "onstat -g ses",
and I run this in dbaccess, it runs very quickly (sub second).
Current SQL statement :
select unique waybill_no from waybill_ref where waybill_ref.ref_no='18405'
The user says that on his side, the program seems to be hanging. Has anyone
had similar experiences on HP & IDS 9.21FC1 ?
We get this every now and then, the program will sit right on top for a
couple of minutes and then disappear again.
I don't know if this is an Informix problem or an HP problem, and I have
people thinking its the database because they can see the current sql
statement sitting there and not changing. I also get the status - cond wait
(netnorm) - when I run onstat -g ses, which I am not too familiar with,
accept that I think the program is waiting for response from another
process.
