http://bugzilla.novell.com/show_bug.cgi?id=572783#c0 Summary: Socket async io thread not cleaned up properly when mono_jit_cleanup() is called Classification: Mono Product: Mono: Runtime Version: 2.6.x Platform: x86 OS/Version: Windows Vista Status: NEW Severity: Critical Priority: P5 - None Component: io-layer AssignedTo: lu...@novell.com ReportedBy: a...@unity3d.com QAContact: mono-bugs@lists.ximian.com Found By: Customer Blocker: No Created an attachment (id=338108) --> (http://bugzilla.novell.com/attachment.cgi?id=338108) Patch that includes a repro case and potential bug fix Description of Problem: Initially, this bug came in as a browser crash with the Unity player. The developer was using async socket requests from managed code. When the window with the Unity content was closed, Unity shut down and cleaned up mono in the process, however, the async io request thread was still running even after mono had shut down. I was able to recreate the problem in a standard application using the "teste" sample. I also have proposed a patch that seems to fix the problem, however, probably needs a seasoned mono dev to review the changes and make the fix more robust. Steps to reproduce the problem: 1. Apply the patch to the 2.6.1 packaged source distribution. 2. Comment out changes to mini.c and gc.c. 3. Compile the test.cs with mcs. 4. Build the "teste" sample and run with the assembly from #3. 5. Watch it go boom. It's a timing issue, so if it doesn't happen the first time, then after a few repeated attempts it should. 6. Comment back in the changes in mini.c and gc.c and re-run test. Actual Results: Crash in async_io thread. Expected Results: Mono shuts down and all threads properly. How often does this happen? Frequently Additional Information: My observations as a "newb" to Mono code: * the domain was not signaled as being unloaded during a mini_cleanup() * async_invoke_io_thread may need additional synchronization for cleanup if mono_thread_pool_remove_domain_jobs() is not sufficient -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ mono-bugs maillist - mono-bugs@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-bugs
