[sipXtapi] SipClient task does not terminate (macosx)

[Paulo Vicentini]

Hi,

I am coping with an issue while calling sipxUnInitialize (mac os x):



stack:

OsTaskBase::delay() /sipXportLib/src/os/OsTask.cpp:122 0x001e46d8

OsTaskBase::waitUntilShutDown() /sipXportLib/src/os/OsTask.cpp:255

SipClient::~SipClient()

...

...

if(isStarted() || isShuttingDown())

{

#ifdef TEST_PRINT

osPrintf("SipClient::~SipClient waitUntilShutDown\n");

#endif

waitUntilShutDown();


---->

UtlBoolean OsTaskBase::waitUntilShutDown(int milliSecToWait)

{

// If task is already shut down, just return.

if (isShutDown()) ---->>>RETURN FALSE (SHUTTING_DOWN != SHUT_DOWN)

return TRUE;

....

.....

// wait up to another nineteen seconds (20 total) for the task to terminate

// printing out a console complaint every second

if (isShuttingDown())

{....


// Do not exit if not shut down

while (isShuttingDown())

{

OsSysLog::add(FAC_KERNEL, PRI_ERR, "Task: %s failed to terminate,
waiting...",

taskName.data());

delay(300000);


/********************/

I will try to find out what is preventing SipClient task to return from its
run method

Do you have any suggestion?


Thanks

It seems that the blocked poll (-1) is not returning after shutting down the
socket so that SipClient does not exit from its run method.
I made a test putting a timeout while calling isReadyToReady(15000) and
SipClient returned since poll had returned too due timeout
OsSocket::close()
...
...
// This forces any selects which are blocked on
// this socket to return
shutdown(tempSocketDescriptor, SHUT_RDWR);
It seems this is not the case with mac os x
What do you say about that?

Thanks
Paulo
