<p><font size="2" face="sans-serif">You are right about the "removeSocketDescription" my explication was not good, forget about this. I should not have waste time trying to find an explanation because I don't have a clear view why this is happening. However this is what I have found so far, if this can help anybody track this down.</font><br>
<br>
<font size="2" face="sans-serif">So it first start with a readSocket failure on socket X, this trigs a deletion if SocketDescriptor, this I am sure.</font><br>
<br>
<font size="2" face="sans-serif">Now I do see that just after that background handling is turned on again on the socket X, just when a new TCP client connects using socket Y and is asking for the stream. Right after that boom... bad file descriptor error.</font><br>
<font size="2" face="sans-serif">This new background handling comes from a call in RTPInterface::startNetworkReading, this is what I found by logging all access to all TCP sockets in the code. </font><br>
<br>
<font size="2" face="sans-serif">It looks like something is not cleaned up properly when the readSocket failure occurs. I will try to create a test that reproduces the problem easily because so far this is very hard to repro, it is a question of having the right timing. Hope this help.</font><br>

-> SocketDescriptor::tcpReadHandler1 line 422<br>
If readSocket fails (-1) it triggers a deletion of the SocketDescriptor object</font></ul>
<br>
<font size="3" face="serif">Correct.</font>
<ul style="padding-left: 36pt"><br>
<font size="2" face="sans-serif"><br>
However this is leaving a dangling pointer in the HashTable in RTPInterface (lookupSocketDescriptor)</font></ul>
<br>
<font size="3" face="serif">Incorrect - because the "SocketDescriptor" destructor calls "removeSocketDescription()", which will remove the "SocketDescriptor" object from the hash table.</font><br>
<br>
<font size="3" face="serif">(Note that the "SocketDescriptor" destructor also calls "turnOffBackgroundReadHandling()" on the socket, so that this socket will no longer get used in the event loop's "select()".)</font><br>
<br>
<br>
<font size="3" face="serif">As I noted earlier, the "bad file descriptor" error (or other socket error) in "select()" is caused by a socket getting closed somewhere without "turnOffBackgroundReadHandling()" also being called for the socket. It's conceivable that there is a bug in the LIVE555 code somewhere that is causing this to happen - in which case I invite people to try to track it down. However, what you described above is not it.</font><br>
