Cache only nameserver

[Daniel Puka]

Hello All, 

  We have a cache only name server that is running HPUX 11.00 with only 256M 
and bind 9.2.2. 

  Our max data size is 128M and the server was running ok for many months 
but in the last days it start to stop working every day and we got out of 
memory log messages. 

  I need some help about the parameters cleaning-interval and max-cache-ttl. 
Our traffic to the server is about 700 Kbps during the peak yours and 
usually the bind crash happen during this time. The named process stop 
answering the queries and after restart it works fine for some hours. 

Thanks, 

Daniel
