Hi,
We use php script to call remote ice grid service, and find the following error message: 
Ice_UnknownLocalException::__set_state(array( 'unknown' => 'ConnectionI.cpp:1308: Ice::ConnectTimeoutException: timeout while establishing a connection', 'message' => '', 'string' => '', 'code' => 0, 'file' => '/home/okooo/web/data3/Html/passStatTest.php', 'line' => 22, 'trace' => array ( 0 => array ( 'file' => '/home/okooo/web/data3/Html/passStatTest.php', 'line' => 22, 'function' => 'computepassstatbyid', 'class' => 'Ice_ObjectPrx', 'type' => '->', 'args' => array ( 0 => '7822199', 1 => 'WCFourGoal', ), ), ), ))
will anybody know how to resolve this problem? And here is my network tracing:

    Hi,

    The trace information indicates that the client is able to open a socket connection to the server at both of its endpoints (192.168.8.30/57732 and 58.83.184.30/57732). Once an Ice client successfully opens a socket connection, it waits for the server to send an initial handshake message, after which the Ice connection is considered to be fully established.

    It appears your client is using a 5s timeout and that the client is not receiving the server's initial handshake message within this timeout period, therefore it reports a ConnectTimeoutException. The most likely reason for a server to fail to send this handshake message is thread starvation, that is, no more threads are available in the server-side thread pool to accept the new connection and send the message. In this situation we generally recommend attaching a debugger to your server to examine the state of all of its threads. Is it possible that your server's thread pool threads could all be busy?

    If you're still having trouble, please specify the versions of Ice and your operating system and compiler.

    Regards,
    Mark
