BIND 8.2.1 - HANGS

[Daniel Andersson]

Hello!

We seems to have a problem with our BIND 8.2.1 and i have seen that im not
alone with the problem! The thing is that Bind 8.2.1 suddenly hangs,
sometimes it recover itself.. Sometimes an strace -p <pid> does the stuff
but not always, one strange thing is that it seems like named is doing
stuff and even writes to syslogd. There is one thing that i have seen when
im have inspected the logs and that is when an unapproved update or AXFR
occurs named stops to answer queries. I did an strace -p <pid> on named
when it died last (i dies werry often here) and the output is here :

We are running Redhat 6.0 and have installed named from the following RPM
package "bind-8.2.1-3.i386.rpm" wich says in the startup :

"Aug 10 07:40:44 ritz named[7790]: starting.  named 8.2.1 Fri Jul  9
13:48:52 CST 1999
^Iroot at nickpc.tyee.vtc.edu.hk:/usr/lib/src/redhat/BUILD/bind-8.2.1/src/bin
/named "

I hope that someone has an good solution to this problem.
