SUGGESTED FIX src/share/vm/runtime.os.cpp (new vs old) 591,597d590 < // Load up sp, fp, sender sp and sender fp, check for reasonable values. < // Check usp first, because if that's bad the other accessors may fault < // on some architectures. Ditto ufp second, etc. < < uintptr_t usp = (uintptr_t)fr->sp(); < if ((usp & (sizeof(address) - 1)) != 0) return true; < 599,600c592 < if ((ufp & (sizeof(address) - 1)) != 0) return true; < --- > uintptr_t usp = (uintptr_t)fr->sp(); 602,603d593 < if ((old_sp & (sizeof(address) - 1)) != 0) return true; < 605d594 < if ((old_fp & (sizeof(address) - 1)) != 0) return true; 617a607,610 > // see if old_fp and old_sp are correctly aligned > if ((old_fp & (sizeof(address) - 1)) != 0) return true; > if ((old_sp & (sizeof(address) - 1)) != 0) return true;

EVALUATION Using a 5.0_08 version of Hotspot with a revised is_first_C_frame (see suggested fix), I ran specjbb2005 in an infinite loop for 6 days on burl-6800-2-a.east (a 24-way 750mhz serengeti) up 48 warehouses using these switches -d64 -Xbatch -Xms8G -Xmx8G -Xss256K -XX:+UseParallelGC -XX:ParallelGCThreads=8 -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -XX:+PrintCommandLineFlags -verbose:gc -XX:+ShowMessageBoxOnError If there's still an underlying SIGBUS problem, it appears to have either been fixed since 5.0_06, or to be NR.
