iOS-NTP crashes after a while?

[timothydevm]

Hello I hope you still read this,

I'm building an application with ios-ntp it works fine however, If the application is in the background for a while and I re-open it it crashes with "exited abnormally with signal 13: Broken pipe: 13"

This has probably something to do with the socket that disconnects at the server side.
Is there a way I can program my App to close the NTP socket when It enters the background so It doesn't crash?

Here are the breakpoints (in AsyncUdpSocket.m source http://pastebin.com/tuKqpnqZ):
[self doSend:[self socketForPacket:theCurrentSend]];

result = sendto(theNativeSocket, buf, (size_t)bufSize, 0, dst, (socklen_t)dstSize);

iPhone backboardd[28] : Application 'UIKitApplication:nl.app[0x8f48]' exited abnormally with signal 13: Broken pipe: 13

Thanks in advance!
