We have been experiencing problems with our named processes core dumping
with the following syslog messages:
Nov 9 10:05:20 achilles named: insist: critical: ns_main.c:537:
rrno == EINTR): Invalid argument failed.
Nov 9 10:05:20 achilles named: ns_main.c:537: INSIST(errno ==
valid argument failed.

signal 6 (
This started several weeks ago. We were running bind 8.1.2. Nothing in
syslog files are stands out as a glaring problem.
We have upgraded to servers 8.2.1 and 8.2.2 P4, but named still keep
The crashes can take place any time from minutes to weeks apart of the
I tracked the problem down in the source code to the evGetNext function
call in ns_main.c. Somehow the function is being entered with the
EV_POLL and EV_WAIT flags set, even through evGetNext is called from
ns_main with only the EV_WAIT flag at the point of the core dump.
I can't seem to track the problem down a definitive event or action.
