Installer hanging for any installer after uptime of X hours

Number:rdar://7105069 Date Originated:7/30/09
Status:Open Resolved:
Product:Mac OS X Product Version:10.6 (10A421a)
Classification:Serious Bug Reproducible:Sometimes
After a restart, the installer app (for stuff like iWork or the iPhone SDK) works fine. However, after an undetermined amount of uptime, it will start to fail, and just never leave the "Preparing Installation" phase.  The only console message is this:

7/30/09 9:01:37 AM	Installer[38184]	*** -[NSMachPort handlePortMessage:]: dropping incoming DO message because the connection or ports are invalid


iPhone Simulator conflict confirmed

I can also confirm that quitting the iPhone Simulator is a workaround for the Software Update problem. No reboot or login/off was necessary for me too.

SnowLeopard 10C540, gcc 4.0.1 (5493), gcc 4.2.1 (5575) (dot11), gcc 4.2.1 (5646) (dot 1), gcc 4.2.1 (5646) (LLVM build 2206) Software Update version 4.0.2 (256)

Same for me, quitting iphone simulator fixes the problem.

Confirmed conflict with iPhone Simulator

I was having the same, and got to this page via google. I confirm that quitting the iPhone Simulator, then retrying the same installs that used to just freeze suddenly work. No reboot or login/off was necessary for me. This started happening with Snow Leopard and Xcode 3.2.

Conflict with iPhone Simulator

Looks like quitting the simulator is a work-around:


Upgraded to Snow Leopard and the problem started.

I can do an install perfectly fine right after a reboot, but after a certain amount of time, any installer I run hangs at the start of copying files, after agreeing, authorizing, etc.

Confirmed here - workaround is logout/login

Seen on two 10.6/10A432 systems here; logging out and back in worked around the issue (no full restart needed).

Same here

All Installer hanging when the machine runs for some undefinded time. After a reboot they work Version 10.6 Retail Build 10A432, installed as an update from 10.5

I get this too, same error message. Rebooted helped. You've been able to reproduce it?
