[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.

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

The OS is Ubuntu with OmniORB 4.1.2.


Any help or hint on this?

Were the hundreds of threads really there? Your subject line suggests
they were in recv(), which seems rather more likely.

Can you try with the current development cut in the 4_1 branch, or this
snapshot?
