Managers, sorry about the delay, I was trying other solutions and spent

After monitoring the

These had the following problem discriptions,

Problem Description:

4208656 in.named 8.1.2 panics - Not enough space failed.
##This one may explain why when limiting cache it would crash, but I am no
expert here and am probably wrong :-)

4284409 libresolv does not protect itself from netscape provided poll

(from 106938-03)

4299852 four vulnerabilities have been found in BIND.

(from 106938-02)

4211042 Bind 8.1.2 in.named memory leak in Solaris 7
##This I presume is the fix to in.named taking up 800+ MB of memory.

(from 106938-01)

4134616 in.named can hang when calling res_mkquery
