DNS stability

[Fabien Dachicourt]

Hi,
I'm runing Bind 8.2 on a linux machin with red hat 6.0 and kernel 2.2.
The Pc is a P133 with 64Mo of memory, and is handle around 1000 zone for a
load average of 2 query each second.
Scince it started, i have some stabilty trouble with it. The DNS answer
every query with a response time of 0.03s, but almost every 2 or 6 hour, i
have an unable to connect the server for around 15 min( at worse 30 min),
and without i do nothing, i restart to answer query normaly, and again few
hours later not answer...
During the time the serveur don't response to query, i'm able to connect to
it via the ftp, ping or do everything else.
The CPU (average of 4%) and Mermory (10% free all the time and i seem to
never used the swap) look good enough for named.

did someone have any idea of what goes wrong. Do i need to upgrade to 8.22P5
to solve this or is it something else.

Thank in advance for your answer
