Mach exception in iPhone

Question

I sometimes get following exception:

[Mach] exception: 0x%x, count: %d, code: 0x%llx 0x%llx
[Mach] Skipping registered port - it is invalid
[Mach] Skipping registered port - mask does not match
signal %d, info %p, uapVoid %p

I do not have any idea what these exceptions are about. Can somebody throw any light on this?

are you getting this error message on simulator or iphone device? — Pawan Rai, Jun 05 '14 at 10:03
I am getting this on iPhone 5S. However, I do not get any such exception if I run it on iPhone 5. — Udit Agarwal, Jun 05 '14 at 10:46
I'm experiencing the same problem. I don't do any special things, it happens suddenly. — Alexey Golikov, Mar 02 '15 at 13:12

try enabling the interception of generic exceptions:

in the left side of xcode, select "breakpoint navigator", on the bottom of left side click on "+", select "add exception breakpoint", a new item named "all exception" added in the breakpoint list. after click again on "+", select "add symbolic breakpoint", and write [NSException raise] inside text area named "symbol".

Now try again run your project.
