Hello,

I have a 5.8 Generic_117350-26 (Sunblade 1600), Bind 9.2.5.  I am
getting some errors which are causing the server to be unresponsive and
crash, however named is still running.  When I start/stop named, it is
fine.  This has already happened 2 times after production a week ago.  I
just took away the datasize, and stacksize options.  I am hoping it was
not these options that caused the failure.  I have seen a similar user
query about 9.2.4 on google, but I did not see a response.  I thank
everyone in advance.

Named.conf:

        //      
        directory "/var/named";
        // query-source address * port 53;
        pid-file "/var/run/named.pid";
        statistics-file "/var/run/named.stats";
//        stacksize 30M;
//       datasize 20M;
        auth-nxdomain yes;                 // v9 wants this?
        allow-transfer { x.x.x.x; x.x.x.x; x.x.x.x; x.x.x.x;
 x.x.x.x; };   // this limits ALL zones
        transfer-format many-answers;      // faster tranfers
        version "djbdns";              // hide BIND version

        recursion       yes;
