iPhone crash, ASIHTTPRequest or NSURL related
Given the following symbolicated crash log, is it more likely that the crash occurred due to the ASIHTTPRequest on Thread 5 or the NSURLConnection on Thread 3? I ask because this question has similar issues: ASIHTTPRequest, EXC_BAD_ACCESS when request did finished
However, they had more around their ASIHTTPREquest crash and it was on Thread 3 whereas my NSURLConnection is on Thread 3 with more info than the other.

As other's have said, there's not enough information in the crash dump to tell if it's the NSURLConnection or the ASIHTTPRequest thread that might be involved, and the console output may help.
However, given past experience, it seems that the chances are that it involves ASIHTTPRequest.
What version of ASIHTTPRequest are you using?
The most common problem people have with ASIHTTPRequest is issues with request vs delegate lifetime, so I'd recommend double checking that in every object you have that can be a delegate to an ASIHTTPRequest (or an ASINetworkQueue) has in the dealloc method:
[request cancel]
[request setDelegate:nil];
[request release];
This should be done for every potentially active request.
JosephHGoogled for objc_exception_throw __NSThreadPerformPerform and found this question with similar crash backtrace ... your exception might be the same missing selector thing. In that thread Brad Larson suggests "going to your build settings and adding -Wundeclared-selector in the Other Warning Flags" to maybe catch this at compile time.
objc_exception_throw 8 or 9 down in the stack indicates, of course, an exception was thrown. you want to look in the device's console log (or xcode's run console if running in the simulator) to see if a message was logged before crashing.
(i have a bone to pick with os x & ios crash reporting, why aren't a bunch of the last lines logged to the console included in the crash report? that would be very helpful for a many kinds of crashes).
Pierre HoustonIt turned out to be a Three20 issue. When I initially installed it, I had to change some linker flags in the build settings. Those flags weren't changed for my distribution build, just my debug one. So the App Store people were seeing it crash because those necessary flags weren't there. Stupid mistake.
joshholatAs far as I know, the problem is in Thread 5:

**6 StageBloc 0x00032a08 +[ASIHTTPRequest runRequests] (ASIHTTPRequest.m:4269)**
ASIHTTPRequest could be the problem. Try update the ASIHTTPRequest to the lasted version: http://allseeing-i.com/ASIHTTPRequest/
Tuyen NguyenI used this as
[request clearDelegatesAndCancel];
request = nil;
