[omniORB] cannot create a worker

[Renzo Tomaselli]

Hi all,
one of our server applications - running on AIX 5.2 and based on Omniorb
4.03 - after a few weeks of uninterrupted service started to output "Cannot
create a worker for this endpoint ...".
Since then, this server was unable to service any further incoming call from
the client application, which is on the same host, it's written in java and
it uses Jacorb for communicating with the server.
Needless to say, restarting the server enforced a proper resume of its
service.
I guess that message was due to missing resources - likely threads - but
this is the very first time I see this message since several years of
Omniorb usage.
Before I dive into the related code, had anyone similar experience ? Any
suggestion ?
Thanks,

Renzo Tomaselli
