Serius Problem

[Janet Dueck]

We are running bind 8.2.1 with patch1 applied on solaris 2.6.  
On the server with the heaviest load named occasionally dies.
It may run for two weeks without a problem and then die twice
in one day.  There are no errors in syslog - named entries just
stop.  There isn't even a core file.

Will this patch solve this problem? 

Is there a list of patches and the problems they solve?

Thanks
