I am having random EXC_CRASH crashes and I think that I have narrowed it down to NSURLConnection. One thing to note, is that I am calling the following in a background selector, could this be an issue?
I am receiving NSData from the following NSURLConnection method:
NSString *urlStr = [NSString stringWithFormat:@"%@",url];
NSURL *serviceUrl = [NSURL URLWithString:urlStr];
NSMutableURLRequest *serviceRequest = [NSMutableURLRequest requestWithURL:serviceUrl];
[serviceRequest setHTTPMethod:@"GET"];
[serviceRequest setCachePolicy:NSURLRequestUseProtocolCachePolicy];
[serviceRequest setTimeoutInterval:30.0];
NSURLResponse *serviceResponse = nil;
NSError *serviceError = nil;
// Get the downloaded data
NSData *returnedData = [NSURLConnection sendSynchronousRequest:serviceRequest returningResponse:&serviceResponse error:&serviceError];
// Do stuff with returnedData;
Crash log:

Just use ASIHttpRequest like everyone else. Easy.
The only alternative, is rewriting (for absolutely no reason) the 5,000 lines of code in ASIHttpRequest.
It is the only solution.
