Out of Memory Problem

[puka]

Hello All, 

  I am running a cache only resolver(bind 9.2.2rc1) on a HPUX 11.00 machine 
with 256Mb memory(A400 server). The server is dedicated only to bind. Every 
time that the cache size gets around 65Mb the server stop to resolv named, 
but the named still running. The only thing that i notice on the logs is the 
following message... 

Oct 27 22:10:48 resolve1 named[8873]: Oct 27 22:10:48.937database: warning: 
cache cleaner could not create iterator: out of memory 

This is happening during the most busy hours of the day when the resolver is 
getting about 500 reqs/sec. Is there any change that i am running out of 
memory? How can I limit the cache size? 

Attached are the top and the syslog messages. 

Daniel
