SIGPIPE exception in iOS Project With BUMP API Integrated

Question

I am experiencing a SIGPIPE error in my Xcode Project. This error has been started showing since one week before. If I commented this method call : [self configureBump]; everything works fine. I had integrated BUMP API in my project. This API is working till one week before without any problems. I am not sure about the cause of this error. Could anyone please help me to resolve this error? Some of My friends are also reported this error.

Xcode Version : 4.5 iOS Version : iOS 6.0/iOS 5.0

Please see the below Stack Trace :

There's a possibility that SIGPIPE being thrown on socket timeout or no/lost connection inside that lib. There might be some server failure on their side or something.

You can get around by ignoring SIGPIPE with:

signal(SIGPIPE, SIG_IGN); 

or

signal(SIGPIPE, SO_NOSIGPIPE);

Check this link for details.

On the other hand, you can debug further by setting your handler function with

signal(SIGPIPE, yourHandlerFunc);

and checking state of sockets/ivars/etc in it.
