I have upgraded the bind to 9.4.3b2. However, it would exit after 7 or 8
hours. 
#uname -a

SunOS dns1 Generic_120011-14 sun4u sparc SUNW,Sun-Fire-480R

The error is :

16-Jul-2008 22:34:48.764 general: critical: resolver.c:5494:
REQUIRE((((query) != 0L) && (((const isc__magic_t *)(query))->magic ==
