I am finding that my object implementation on Linux hangs up rather than reporting an exception when it hits the user's process limit. I have reproduced the problem with a small change to the "echo" example eg2_clt/eg2_impl:

echo.idl: 
Add a second parameter, "in short pause", to the echostring operation.

eg2_impl.cc:
Modify the echostring implementation to sleep for the number of seconds specified by "pause" before responding (so that the threads for a number of echostring calls can be present simultaneously). 

eg2_clt: 
Call echostring with a 2 second pause.

... and run with uname -p set such that the process limit will be reached if more than one call to echostring is in progress at a time.


Consecutive runs of eg2_clt work OK. However, if it is run a number of times simultaneously (so that threads are present for multiple echostring calls and the thread limit is reached): 
- The first client to run after the limit is reached gets a COMM_FAILURE and terminates.
- All subsequent clients fail get an echostring response or to terminate.
- The implementation does not terminate.


Thanks very much for any help.
Gail.
