[arch-general] bind/named dying after 24-48 hrs. "assertion failure"?

[David C. Rankin]

All,

  Has anyone else encountered a bind 9.13.4-1/named daemon dying with
"assertion failure" in the past week. I have encountered the problem twice.
When named dies, status reports:

  This hasn't happened before. A simple restart makes it happy again -- but
for how long?

  I don't know if this is somehow related to the timers and keys that may be
timing out after some period of time. If no one else has seen this, I'll keep
watching, but if anybody has any ideas, I'd welcome your thoughts.
