What steps will reproduce the problem?
1.
SLES 11.3 with slightly patched 3.16 kernel
Linux memcached9 3.16.3-4.1.100-default #1 SMP Thu Sep 18 06:32:16 UTC 2014
(d2bbe7f) x86_64 x86_64 x86_64 GNU/Linux
64 Gig total memory
memcached 1.4.24, built from source with
CFLAGS="-g3 -O3" + --disable-coverage
2. memcached started as
/usr/sbin/memcached -d -F -m 60000 -k -u nobody -p 11211 -c 65535 -t 12 -o
lru_maintainer lru_crawler hash_algorithm=murmur3 slab_reassign
3. crashes with
[1565425.309019] traps: memcached[17639] general protection ip:4123a7
sp:7feade1ece70 error:0 in memcached-1.4.24-33[400000+20000]
$ addr2line -e /usr/sbin/memcached 4123a7
memcached-1.4.24/items.c:1183
we use lru_crawler quite a bit and have custom scripts that use "slabs
reassign" to move memory between slabs based on slabs stats (i.e. in house
custom slab reassign).
As an anecdote, 1.4.21 occasionally falls into infinite loop under these
conditions as well, and we were trying to fix that by upgrading.

crap, I wish I saw this sooner.
What is your items.c:1183?
It looks like:
if (it->prev) {
it->prev->next = it;
}
^ middle line.
I'd love to know how that's possible. any chance of getting a backtrace?
