Hi,
[ CC'ed to two persons that I suspect they've been hit by this issue too ]
In the last two days we had two signal 6 (ABORT) bind crashes which
were triggered by a software assertion:
Oct 8 15:43:40 quark /kernel: Oct 8 15:43:40 quark named[38899]:
/usr/src/usr.sbin/named/../../contrib/bind/bin/named/ns_maint.c:274:
INSIST(zp->z_time == 0 || zp->z_time > tt.tv_sec) failed.
Oct 8 15:43:40 quark /kernel: Oct 8 15:43:40 quark /kernel: pid 38899
(named), uid 53: exited on signal 6
Oct 9 14:44:21 quark /kernel: Oct 9 14:44:21 quark named[42553]:
/usr/src/usr.sbin/named/../../contrib/bind/bin/named/ns_maint.c:274:
INSIST(zp->z_time == 0 || zp->z_time > tt.tv_sec) failed.
Oct 9 14:44:21 quark /kernel: Oct 9 14:44:21 quark /kernel: pid 42553
(named), uid 53: exited on signal 6
The relevant code from bind/bin/named/ns_maint.c is:
/*
* It is essential that we never try to set a timer in the past
* or for now because doing so could cause an infinite loop.
*/
INSIST(zp->z_time == 0 || zp->z_time > tt.tv_sec);
sched_zone_maint(zp);
Environment:
FreeBSD quark.warpnet.ro 4.4-PRERELEASE FreeBSD 4.4-PRERELEASE #0: Tue Aug
7 18:11:12 EEST 2001 root@quark.warpnet.ro:/usr/obj/usr/src/sys/QUARK
i386
named 8.2.4-REL Tue Aug 7 12:20:09 EEST 2001
root@quark.warpnet.ro:/usr/obj/usr/src/usr.sbin/named
Has anyone else experience this ? Is there a fix commited into the CVS
tree for this ? Does 8.2.5-REL fix this (BTW, it hasn't been yet committed
to the FreeBSD CVS repository; the bind8 port hasn't been updated either)?
Please no "update to current -STABLE, maybe it's been fixed" :-) ...
it's a production server and I prefer to check this out before I jump on
the CVSup bandwagon.
Thank you,
Ady (@warpnet.ro)
