It sounds like you may have a deadlocking problem in your app

Hi Chuck,
After more investigation, the WO Adaptor receives the request and send
to application's instance and
wait 45 sec. for a reply. The instance never respond but wotaskd is
able to shutdown it. I've changed
the minimum sessions to 10 like that wotaskd is able to restart
instances every day.
If you can get a thread dump (see the archives here or on Omnigroup)
that should show if this is the case.
Seems to be used only from Terminal, in my case the application is
always working fine during development
it's only while running on deployment that this problem happened.
Is it possible to get a thread dump of deployed instance?
Are you being careful to lock and unlock all of your editing contexts
correctly?
Yes I do, each new EOEditingContext is lock/unlock:
ec.lock();
try {...}
catch {...}
finally { ec.unlock(); }
but I never lock/unlock the defaultEditingContext. I'm wondering if
it's required in some context?
What is your experiences about the defaultEditingContext?
BTW, I'm using Oracle database and I can see in the ora trace log that
there are deadlocks.
EOEditingContext lock/unlock are useful in the same instance but what
about between instances,
my application have 10 instances. I've a ILLRequestLock table used when
I have to lock
a ILLRequest row to allow only one writer and many readers.
Is it required to lock/unlock editing context where all the entities
are read-only in EOModeler?
Thank you for your help.
Cheers,
Daniel
