Something in r291926 (and earlier) causes reboots during periodic daily (14 jails on system)

Hi,

with r291381 a system with 14 jails survives about 1-2 days.
with r291926 this system survives 1 day.

In both cases it reboots during periodic daily (the jails run periodic
too, at the usual time). This is a ZFS-only (+nullfs) system

There is no coredump. Watchdogd is currently not enabled on this
system. In the logs I don't find any traces.

The system is not really low on resources:
last pid: 18031;  load averages:  0.25,  0.23,  0.80      up 0+03:59:05  08:57:12
189 processes: 1 running, 188 sleeping
CPU:  0.3% user,  0.0% nice,  0.4% system,  0.1% interrupt, 99.1% idle
Mem: 579M Active, 709M Inact, 2311M Wired, 8253M Free
ARC: 1460M Total, 418M MFU, 868M MRU, 1946K Anon, 17M Header, 155M Other
Swap: 4096M Total, 4096M Free

Does this ring a bell for someone or any ideas before I try to hunt
this down?

Bye,
Alexander.
