Debug log
I have a simple multithreaded client to singlethreaded server test that works
fine from JacORB 2.4 - 3.3 which started throwing COMM_FAILUREs at me starting
with JacORB 3.4 (but also in 3.5).
The test implements a trivial client for the following IDL:
interface Foo
{
string get_string(in long tid);
};
The server creates and activates a single servant and executes ORB#run in the
main thread.
The client resolves the servant reference, starts 2 threads and calls the
servant's get_string() method 10 times in each thread.
The client uses DII and the server DSI.
When running this with either JacORB 3.4 or 3.5 at a certain point in the
iterations COMM_FAILUREs appear. Detailed logging seems to suggest connections
are being unexpectedly closed at some point.
Attached a debug log of a fairly typical testrun.
Any ideas why this may have started happening from JacORB 3.4?</pre>
