Recently, any time I tried to run Safari on 10.6 caused all apps and the Finder to hang with the spinning beach ball.
Force-quitting Safari stopped the problem, but it would occur again on the next launch. Googling around, I saw many folks reporting similar problems, but no solutions.
The /var/log/system.log file shows something like this when this hang occurs:
Nov 13 09:51:16 bvmbook Safari[394]: INSERT-HANG-DETECTED: Tx time:46.498542, # of Inserts: 0, # of bytes written: 0, Did shrink: YES
Sounds like a database problem. So I looked at which database-type files were opened by Safari, with this in Terminal:
I found that if I quit Safari and deleted the *.db files in my home directory, the problem goes away:
I'm not sure which of these files were corrupt, but launching Safari seems to re-create them.
