Hang in _openProtocol::: when launching listener twice #1
Description
When I'm lauching a listener, shut it down and launch it again, the call to [listener open] never returns. It seems deadlocked with thread 6.
Complete backtraces of all threads below
Code to startup and shutdown
(void)startup
{
if (browser != nil)
return;
browser = [[MYBonjourBrowser alloc] initWithServiceType:@"_rtxxxdata._tcp."];
registration = [[browser myRegistration] retain];
listener = [[BLIPListener alloc] initWithPort:12345];
[listener setPickAvailablePort:YES];
[browser start];
[listener setDelegate:self];
[listener open];
[registration setPort:[listener port]];
[registration start];
}
(void)shutdown
{
[browser stop];
[registration stop];
[listener close];
[listener setDelegate:nil];
[browser release], browser = nil;
[registration release], registration = nil;
[listener release], listener = nil;
