BIND 9.7.3-P3 crash on multiple cashing servers

[Frank Bulk]

We had the same thing, affected only one of our DNS servers (behind a
load-balancer).  Here's the relevant log snippet:

8 of our cashing-only name servers crashed in a random sequence, and the
crash happened in a 10 minutes time. The servers are running BIND 9.7.3-P3.

 

The crash produced a core dump for the named process.

 

Does anybody has a similar case recently? Is this a security issue ?

Samer
