BIND 9.2.3 Crashes with rbt.c ....

[Yar Baily]

Hello all,
I have BIND 9.2.3 installed on a Sparc/Solaris 9 machine. It has been operation for almost last 4 months. Just recently it has started giving me the following message when the process dies:

rbt.c ....INSIST (order < 0 ) failed
exiting due to assertion failure.

Could some shed some light on what is happening and what the solution could be ?

Thanks in advance

Yar
