Quartus 10 SP1 crashes often when fitting

[Altera_Forum]

Quartus version 10 seems to crash a lot 1/3 of the time when it gets to fitting. I get a different error most of the time but here are some of the errors. Any help would be appreciated.

As a workaround, you may also want to switch to TimeQuest and try.
