[omniORB] Hundred of threads in recv

[Andrea Venturoli]

Hello.

This morning we had to restart a server application we developed, since 
it was not responding any more.

We saw a lot of this error in the logs:

> omniORB: Exception trying to start new thread (11). Task queued.

Also, there were hundreds of threads like the following:

The OS is Ubuntu with OmniORB 4.1.2.


Any help or hint on this?
