It seems many users having a problem with Mac OS X Snow Leopard freezing, especially after updating to 10.6.1. The freeze up is usually directly related to Spotlight.

Apple’s latest Performance Update 1.0 seems to address this issue. The update can be found here.

However, not all users experiencing this freeze up are eligible for the update.

Try using Disk Utility and running Verify (and subsequently Repair, if necessary) Disk on your hard drive. You should also be sure any third-party software you have running (especially applications that run in the background) are completely up-to-date and Snow Leopard compatible.

Many believe the issue to be related to Apple’s WebKit standard which drives applications like Safari and Mail. The ominous “INSERT-HANG-DETECTED” error message is the most common thread in Console logs from reporting users, suggesting some sort of network issue.
