bind-9.2.1-16 stop answering requests on RH9

Thu Jun 30 15:26:56 UTC 2005

Dear Sirs,
I have a Bind server (bind-9.2.1-16) running on RH9, which randomly locks.
It has been running for two years. 
As far as I know, any child process is terminated and only parent
process stays running (?). In "ps axf" output, displays:
16042 ?        S     10:13 [named]

But its no longer answering any requests.

I've attached a text file with a portion of my named.log that shows
last lines before bind locked (Jun 29 19:39:57.033) and the first
lines after I issued a "service named restart" (Jun 30 09:35:33.443).

I've checked disk space and other vital signals of the server. Everything is ok.

Could someone give me directions how to investigate this problem ?
