I am using a socket-based NSConnection between machine. Instead of a direct connection I use an SSH-tunnelled TCP connection for the NSConnection transport.
Basically I have a local NSConnection socket client that I connect to server localhost:59595 (for example). At localhost:59595 is a SSH tunnelled connection to the remote machine. On the remote machine there is an NSConnection server at port 60000. This works, except that every request sent across the NSConnection leaks some memory here: 0 CoreFoundation _CFRuntimeCreateInstance 1 CoreFoundation __CFArrayInit 2 CoreFoundation -[__NSPlaceholderArray initWithCapacity:] 3 CoreFoundation -[__NSPlaceholderArray init] 4 Foundation -[NSConnection initWithReceivePort:sendPort:] 5 Foundation +[NSConnection connectionWithReceivePort:sendPort:] 6 Foundation -[NSConcretePortCoder connection] 7 Foundation +[NSDistantObject newDistantObjectWithCoder:] 8 Foundation -[NSConcretePortCoder decodeRetainedObject] 9 Foundation _NSWalkData2 10 Foundation -[NSConcretePortCoder decodeReturnValue:] 11 Foundation -[NSConnection sendInvocation:internal:] 12 Foundation -[NSDistantObject forwardInvocation:] 13 CoreFoundation ___forwarding___ 14 CoreFoundation _CF_forwarding_prep_0 If I setup the SSH tunnel to use localhost:60000 (i.e. so the local server and the remote server use the same port number) then the connection leaks no memory. It seems that NSConnection has some knowledge or dependency on the actual server port vs. the port I'm having it connect to and this is causing a problem. Has anyone ever done anything like this? any ideas on how to eliminate this memory leak per request? Thanks.
