Re: XCode 3.1 frequently hangs



fs_usage is pretty good! Not to get too OT, but is there a place where these special Mac utils are documented? Been doing SW for a while, but that's a new one to me.

tia,
Eric

$ sudo fs_usage -f filesys 48965 | grep lstat

This would just be to tell which file was involved, correct? It's true that
it might tell us something if it's always the same file.



Correct.

Larry, if you could try this investigation with fs_usage, I would appreciate
it. We've had reports of this issue, but we've never been able to reproduce
it under laboratory conditions.



The result of fs_usage showed that it is always the same file:

lstat             net/kpi_interface.h
                         10.154884 W Xcode

All other files are very quick: around 0.000003s


If you run "locate kpi_interface.h", do you get this list?

$ locate kpi_interface.h
/Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/ Kernel.framework/Versions/A/Headers/net/kpi_interface.h
/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/ Kernel.framework/Versions/A/Headers/net/kpi_interface.h
/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/net/ kpi_interface.h


Do any of the kpi_interface.h files hang if you stat them in Terminal? Such as:

$ for file in `locate kpi_interface.h` ; do  stat $file ;  done

If you don't have a "locate" database, just stat each version on the command line.

Do the files open quickly in apps other than Xcode?
