CPU overload caused by Heartbeat-Monitor's timer

[LironGiniApps]

In the file SRKeepAliveData.m there's a calculation in order to determine what is the _checkInterval.

_checkInterval = [NSNumber numberWithInteger:(([_timeout integerValue] - [_timeoutWarning integerValue]) / 3)];

In our case, the server is sending keepAliveTimeout == 6.
So, after calculating the _checkInterval, the result is 0 because the code uses numberWithInteger and also integerValue (instead of using doubles) while trying to pull the data into the Heartbeat Monitor's timer.

When _checkInterval is equals to 0, that means that the Heartbeat Monitor's timer is instantiated with timeInterval == 0, which causes the timer to run every 0.001 seconds and finally a serious CPU overload.

The code for instantiating the timer is in file SRHeartbeatMonitor.m line 50:

_timer = [NSTimer scheduledTimerWithTimeInterval:[[[_connection keepAliveData] checkInterval] integerValue] target:self selector:@selector(heartbeat:) userInfo:nil repeats:YES];

Thank you very much,
