You could try increasing the max heap size we saw alot of SIGBUS 10 crashes with sp4 until we increased this value to 1024 which happens to be the default in 6.5. Turn on garbage collection statistics with -verbose:gc if you suspect this could be the problem. The stack size should be set to about 10% the size of the (entire) registry.
Usually however these errors tend to be code related...
Does the crash happen at the same time everyday.
