Summary0002995: named service crashes with an assertion failed message
DescriptionSince the upgrade to the following:

Version: 9.3.4
Release: 6.0.2.P1.el5_2

We have had an issue with the named service randomly dieing off. In /var/log/messages we see the following errors:

Jul 17 13:00:42 ns-mail named[19409]: socket.c:1649: INSIST(!sock->pending_recv) failed
Jul 17 13:00:42 ns-mail named[19409]: exiting (due to assertion failure)

The server is running bind-chroot and also has the caching-nameserver package installed. In addition to the local related zones, we also have 10 forwards setup in the named.conf file.

This occurred on a fresh install of 5.2 which had the named service running for approximately 36 hours prior to this crash.

A point to also note is that we had a 4.6 server running and this same error occurred on it after the recent BIND related security patches. We then decided to migrate to 5.2, in which we have seen this same issue happen today, thus the bug report.
TagsNo tags attached.

Can you please report that upstream at - if it is not already listed there. A quick search doesn't find anything.

After you did so, can you please put the link to that issue here?

Thank you.
